Answer:

Step-by-step explanation:

Begin by isolating the term with the r in it. Do that by subtracting 8.9 from both sides:

9.5r = -110.445 - 8.9 and

9.5r = -119.345  Divide both sides by 9.5 to get

r = -119.345/9.5 and

r = 12.56263158 (or you could leave it as a fraction)

Answer:

Richard bought 128 total batteries

Step-by-step explanation:

1. Multiply 4 by 4 to find the total batteries in one package

4 * 4 = 16

2. Now we know that there are 16 batteries per package. There are 4 packages in a box. Multiply 16 by 4

16 * 4 = 64

3. 64 represents the total number of batteries in a box. Since Richard bought two boxes, multiply 64 by 2

64 * 2 = 128

Answer:

y = -1|x+1| +1

Step-by-step explanation:

The vertex form of an absolute value equation is y = a* |x-h| +k

a = -1 because it opens downwards with a slope of ± 1. Next it's vertex is at (-1,1). So replace h with -1 and k with one.


y = -1|x+1|+1

Step-by-step explanation:

x is the days that the first team finishes the work alone (x>8)

y --------------------------second-----------------------------------------(y>8)

In a day:

⇒          \(\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}\)               (1)

If the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains:

⇒          \(\frac{2}{x}+\frac{5}{y}=\frac{3}{8}\)                (2)

(1),(2)   ⇒   \(\left \{ {{\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}} \atop {\frac{2}{x}+\frac{5}{y}=\frac{3}{8}}} \right. <=>\left \{ {{x=16} \atop {y=24}} \right.\)

It'll take the first team 16 days and the second team 24 days to finish the work alone

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

     Triangle Inequality Theorem states that two sides of a triangle must be greater than the third side.

     Using this method, the answer is {11, 14, 22} because 11+14>22, 11+22>14, and 14+22>11

x = 67°

Same-side interior angles are supplementary.

     x° + 113° = 180°

     x° = 180° - 113°

     x = 67°

r = 2°

     The little box represents 90 degrees, meaning that these angles are complementary.

     9r + 2° + 70° = 90°

     9r + 72° = 90°

     9r = 18°

     r = 2°

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

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:

Step-by-step explanation:

midpoint of AC=((-3+3)/2,(-5+5)/2)=(0,0)

midpoint of BD=((2-2)/0,(-3+3)/2)=(0,0)

coordinates  of midpoint of AC and BD are same.

∴ AC and BD bisect each other.

\(AC=\sqrt{(3-(-3))^2+(5-(-5))^2 } =\sqrt{6^2+10^2} =\sqrt{136} =2\sqrt{39} \\BD=\sqrt{((-2-2)^2+(3-(-3))^2} =\sqrt{16+36} =\sqrt{52} =2\sqrt{13}\)

Midpoint of AC and BD is ( 0, 0 ), so both bisects each other.

The value of AC = 2 √39 and BD = 2 √13

Here, points given as,

A(–3, –5), B(2, –3), C(3, 5), and D(–2, 3).

We have to find,  AC and BD.

What is distance between two points?

Distance between two points \(P(x_{1} ,y_{1} )\) and \(Q(x_{2} ,y_{2} )\) is given by:

\(d(P, Q) = \sqrt{(x_{2}- x_{1} )^2 +(y_{2}- y_{1} )^2 }\)

Now,

Midpoint of AC = \((\frac{-3+3}{2} ), (\frac{-5+5}{2} ) = ( 0, 0 )\)

Midpoint of BD = \((\frac{-2+2}{2} ), (\frac{-3+3}{2} ) = ( 0, 0 )\)

Hence, Both AC and BD bisects each other.

And, Distance between A and C is,

AC = \(\sqrt{(3 - (-3))^2 +(5 - (-5))^2 } = \sqrt{36 + 100} = \sqrt{136} = 2\sqrt{39}\)

Distance between B and D is,

BD = \(\sqrt{( -2 -2))^2 +(3 - (-3))^2 } = \sqrt{16 + 36} = \sqrt{52} = 2\sqrt{13\)

Answer: b. one solution: (2.5, 0).

Step-by-step explanation:

y = 2x - 5

-8x - 4y = -20

-8x - 4y = -20

-8x - 4 * (2x - 5) = -20

-8x - 8x + 20 = -20

20 + 20 = 16x

16x = 40

x = 40/16

x = 2.5   y = 2x - 5 = 2 * 2.5 - 5 = 5 - 5 = 0

(x, y) = (2.5, 0)

The system of equations will have a unique solution (2.5, 0)

A system of equations is a set or collection of two or more equations with the same variables. The common solutions are the intersecting points of the equations.

Given is a system of linear equations y = 2x-5 and -8x-4y = -20

y = 2x-5......(i)

-8x-4y = -20

Rearranging the equation,

8x+4y = 5

2x+y = 20

y = 20-2x.......(ii)

Solving the equation,

20-2x = 2x+5

15 = 4x

x = 2.5

Put x = 2.5 in eq(i)

y = 2(2.5)-5

y = 0

Now, determining how many solutions do this system has,

Ratios of the coefficient,

1/1, 1/4, -1

Since, 1/1 ≠ -1

Therefore, the system of the equation has only one solution.

Hence, the system of equations will have a unique solution (2.5, 0)
