Step-by-step explanation:

When we're solving with scale factors, we either divide or multiply.

If the shape becomes larger, we multiply to get the new length.

If the shape becomes smaller, we divide to get the new length.

We're given:

Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.

2.5 x 6 = 15

Therefore, the missing side length is 15 units.

Answer:

225 and 243.4

Step-by-step explanation:

Area of triangle = bh/2

A = 4*4.6/2

A = 9.2 cm sq

A of 2 triangles = 9.2*2 = 18.4 cm sq

Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq

A of 3 rectangles = 75*3 = 225 cm sq

Now, LSA = 225 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

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

From the information given, we have that;

The points are;

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

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

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Answer: The inequality solves to x ≥ 42

The graph is shown below

==================================================

Explanation:

We have some unknown number x, and we're dividing by 6 to form the fraction x/6. That result is 7 or larger which means we write x/6 ≥ 7

To solve for x, we undo the division. We'll multiply both sides by 6. That's how we get to x ≥ 42

The graph will involve a number line. Plot a closed filled in circle at 42 on the number line. Shade to the right. This visually represents any number that is 42 or larger. The endpoint 42 itself is included in the solution set.

Side note: We would use an open circle if we didn't have the "or equal to" portion for the inequality sign.

Answer:

51

Step-by-step explanation:

if you have 506 you split it up so you get 500 and 6

but there can't be a container with 6 marbles so you give 10 from the 500 so now you will get 490 and 16 the 490 divide by 10 = 490

after that 16 divide by 8 = 2 so 49 + 2 = 51

Answer:

50

Step-by-step explanation:

I think that if she had limited space she would probably pack the most amount of marbles she could in one container. The Question asks "how many containers had 10 marbles "  So you need to figure out how many containers she used. Saying that she packed 10 in every container, the amount of containers she probably filled up is 50. The six left over in 50.6 which you get when you divide 506 by 10 is left over so only the container will have 6 marbles, not ten, and the question asks how many with ten marbles.

Answer:

-0.58

Step-by-step explanation:

The number gets less as you move to the bottom. Each dash represents 0.01. The dot is 3 lines below -0.55, so you would do -0.55 - 0.03, and the answer is -0.58.

I hope this helps and please mark me as brainliest!

Answer:

-0,56

Step-by-step explanation:

As you go up, the numbers tend to get larger. -0.5 is larger than - 0.6

So considering where the dot is on the number line, you have to subtract - 0.02 for every horizontal line you cross.

Another way of putting this is you must add 0.02.

For me, it is easier to add 0.02 because the amount is getting bigger. Why 0.02? it is because there are 5 horizontal notches between -0.6 and - 0.5. Each notch must be -.1/5 = -0.02

First notch: -0.6 + 0.02 = -0.58

Answer: Second notch: -0.58 + 0.02 = -0,56

Area triangle = 1/2(14*5)

Area triangle = 1/2(70)

Area triangle = 35

Now the area of the square

Area square = 2 * 2

Answer:

Step-by-step explanation:

tamika eats jelly beans at a rate of 3 jellybeans ber miniute since it would be 12/4. and it takes tamika 30 minutes which means that the snack pack had 90 jellybeans.

James eats jellybeans at a rate of 4 jellybeans per miniute so it took james 22.5 miniutes to eat a snack pack.

so you would subtract tamikas minutes(30 min) - james minutes(22.5) and get 7.5 minutes.

James took 7 minutes and 30 seconds less than Tamika to eat his jelly beans.

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

A unit rate means a rate for one of something.

It is written as a ratio with a denominator of one.

We have,

Tamika:

Rate of eating jellybeans = 12 jelly beans per 4 minutes.

12 beans = 4 minutes

Divide it by 4 into both sides

We get,

3 beans = 1 minute ___(1)

Tamika took 30 minutes to finish snack-size beans.

This means from (1),

3 x 30 jelly beans= 30 minutes

90 jelly beans = 30 minutes

There are 90 jellybeans in snack-size beans.

James:

Rate of eating the jellybeans = 28 jellybeans per 7 minutes

It can be written as:

28 jelly beans = 7 minutes

Multiplying 90/28 on both sides we get,

90 jelly beans = (90/28) x 7 minutes

90 jelly beans = 90/4 minutes = 22.5 minutes

This means James takes 22.5 minutes to finish snack-size jelly beans.

We see that,

The time took for Tamika to finish snack-size jelly beans = 30 minutes

The time took for James to finish snack-size jelly beans = 22.5 minutes

we have,

30 - 22.5 = 7.5

Thus,

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

First when you divide 6 and 3/4. We use a dividing a fraction by a whole number. We have to make 3/4 into 4/3 to make it easier because we are trying to have a whole number. Then you multiply 6 and 4 to get 24 then you divide by 3 so you get 24/3. When you divide this, you get 8.

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Answer:

x = 30°

The angles:

Step-by-step explanation:

Hello!

The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.

Solve the equation:

We can replace 30° for all the angles.

The measures are:

2x = 60

3x = 90

x = 30

All triangles have 3 angles that add up to 180 degrees. We can use the information to create an equation.

Finding x

First, add all of the angles together and set them equal to 180

Next, combine like terms

Finally, divide both sides by 6

Solve For Missing Angles

Now that we have x, we can solve from each of the missing angles. Do this by plugging in 30 for the x-values.

2x

3x

x

We can check our answers by adding all of these together. Because 60+90+30 equals 180, these answers must be correct.
