Answer:

x = 3.03

x = 1/2

x = 4/3

Step-by-step explanation:

1. Considering we have a number within and out of a parenthesis, we can first use the distributive property. Multiply the number outside of the parenthesis by both numbers inside the parenthesis.

(2,000 * x - 2,000 * 0.03) = 6,000

2,000x - 60 = 6,000

Now we need to isolate x, first add 60 to both sides:

2,000x - 60 = 6,000

2,000x = 6,060

Now divide both sides by 2,000 to get x alone and have our answer:

2,000x = 6,060

x = 3.03

2. Just like the first question, we have a number outside of the parenthesis and two numbers inside the parenthesis, so use the distributive property:

(2 * x + 2 * 1.25) = 3.5

2x + 2.5 = 3.5

Isolate x, get rid of 2.5 by subtracting it to both sides:

2x + 2.5 = 3.5

2x = 1

Now divide both sides by 2:

2x = 1

x = 1/2

3. Same as the last two, start with the distributive property:

1/4 * 4 + 1/4 * x = 4/3

1 + 1/4x = 4/3

Isolate x, subtract 1 by both sides:

1 + 1/4x = 4/3

1/4x = 1/3

Divide 1/4 by both sides:

x = 4/3

Step-by-step explanation:

hello,

to work out the equation, you need to have the x value on one side only.

for e.g, let's take the first question itself.

1. 2000 ( x - 0.03 ) = 6000

( x - 0.03) = 6000/ 2000

(÷ by 2000 both sides to eliminate 2000 on l.h.s.)

( x - 0.03) = 3

x - 0.03 = 3

(add 0.03 on both sides to eliminate 0.03 on l.h.s)

x = 3 + 0.03

x = 3.03

2. 2( x + 1.25 ) = 3.5

here you have to work out the brackets first. hence,

2x + 2.5 = 3.5

( subract 2.5 from both sides.)

2x = 3.5 - 2.5

2x = 1

(divide both sides by 2 to have x on the l.h.s only)

x = 1/2

3. ¼ (4 + x ) = 4/3

(work the brackets first.)

1 + ¼ x = 4/3

( subract 1 from both sides)

¼ x = 4/3 - 1

¼ x = ⅓

( cross multiply or divide both sides by ¼)

3x = 4 ( by cross multiplication )

x = 4/3

now that you know the answers, try to understand them and do practice them on your own, then check the answers. do let me know if there's anything you haven't understood, or any questions you have.

wishing you a beautiful day !

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

=-3+6x which is what your original equation was.

Step-by-step explanation:

50.2 = 5.02 × 10¹

1102 = 1.102 × 10³

so,

50.2 × 1102 = 5.02 × 1.102 × 10³×10¹ =

= 5.02 × 1.102 × 10⁴

so, the decimal point moves 3 positions to the right :

55,320.4

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.

In other words you get the basic idea, you can also just count, but whatever.

Step-by-step explanation:

You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.

The perimeter of a rectangle is given by the formula ...

  P = 2(L +W)

Filling in the given values, we can find the unknown.

  330 = 2(L +77)

  165 = L +77 . . . . . . . divide by 2

  165 -77 = 88 = L

The length of the garden is 88 meters.

The area of a rectangle is given by the formula ...

  A = LW

Filling in the given values, we can find the unknown.

  6734 = 91W

  6734/91 = 74 = W

The width of the window is 74 cm.

Answer:

I think the number of terms are 3

Answer:

There are 5 terms: 2 is a coefficient, the x are variables, the 2 above the x is an exponent, and 4 is a constant.

Given the following information:

\(\displaystyle\sf n(U) = 50\)

\(\displaystyle\sf n(P) = 28\)

\(\displaystyle\sf n(Q) = 35\)

\(\displaystyle\sf n(P'\cap Q') = x\)

Let's express the requested values in terms of x:

1. \(\displaystyle\sf P'\cap Q\):

Using the principle of complements, we know that \(\displaystyle\sf P'\cap Q = U \setminus (P \cup Q) = U - (P \cup Q)\).

Since the universal set U has 50 elements, and we are given that \(\displaystyle\sf n(P) = 28\) and \(\displaystyle\sf n(Q) = 35\), we can calculate the value of \(\displaystyle\sf n(P \cup Q)\):

\(\displaystyle\sf n(P \cup Q) = n(P) + n(Q) - n(P \cap Q)\).

Since we don't have the value of \(\displaystyle\sf n(P \cap Q)\), we cannot calculate the exact value of \(\displaystyle\sf n(P \cup Q)\). Therefore, we cannot express \(\displaystyle\sf P'\cap Q\) in terms of x.

2. \(\displaystyle\sf P \cap Q\):

Using the same principle of complements, we know that \(\displaystyle\sf P \cap Q = U \setminus (P' \cup Q') = U - (P' \cup Q')\).

Similarly, we cannot calculate the exact value of \(\displaystyle\sf n(P' \cup Q')\) since we don't know \(\displaystyle\sf x\). Thus, we cannot express \(\displaystyle\sf P \cap Q\) in terms of x.

3. \(\displaystyle\sf n(P \cap Q')\):

Using De Morgan's laws, we know that \(\displaystyle\sf n(P \cap Q') = n(P) - n(P \cap Q)\).

Since we are given that \(\displaystyle\sf n(P) = 28\), we need to calculate \(\displaystyle\sf n(P \cap Q)\). Unfortunately, we don't have enough information to find the exact value of \(\displaystyle\sf n(P \cap Q)\) in terms of x. Therefore, we cannot express \(\displaystyle\sf n(P \cap Q')\) in terms of x.

Regarding the greatest and smallest possible values of x, without additional information or constraints, we cannot determine those values. We would need more details or conditions related to the intersection of sets P and Q or other relevant factors to determine the range or limitations of x.

This is a question related to set theory, a branch of mathematics that deals with the properties of well-defined collections of objects1. Here are some formulas that might help you solve the question2:

The complement of a set A is denoted by A’ and it contains all the elements that are not in A.

The union of two sets A and B is denoted by A ∪ B and it contains all the elements that are in either A or B or both.

The intersection of two sets A and B is denoted by A ∩ B and it contains all the elements that are in both A and B.

The difference of two sets A and B is denoted by A - B and it contains all the elements that are in A but not in B.

The cardinality of a set A is denoted by n(A) and it represents the number of elements in A.

Using these formulas, we can express the sets (P’nQ), (PnQ), and n(PnQ’) in terms of x as follows:

(P’nQ) = (P ∪ Q)’ = U - (P ∪ Q) = U - P - Q + P ∩ Q

(PnQ) = P ∩ Q

n(PnQ’) = n(P) + n(Q’) - n(P ∩ Q’) = n(P) + n(U) - n(Q) - n(P ∩ Q)

To find the greatest and smallest possible values of x, we need to use the following formula2:

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

Applying this formula to P and Q, we get:

n(P ∪ Q) = n(P) + n(Q) - n(P ∩ Q)

50 - x = 28 + 35 - n(P ∩ Q)

x + n(P ∩ Q) = 13

Since x and n(P ∩ Q) are both non-negative integers, the greatest possible value of x is 13 when n(P ∩ Q) is 0, and the smallest possible value of x is 0 when n(P ∩ Q) is 13.

I hope this helps you understand the question better.
