Hi there!

Your answer is:

17= 2A-5

Alonzo is 11

Step-by-step explanation:

Frank=2A -5

Frank = 17

17= 2A-5

A = Alonzo's age

Alonzo's age is:

17= 2A-5

22 = 2A

11= A

Answer to letter B , C, D

Feliz [49]

Answer:

See below.

Step-by-step explanation:

Our expression given: 3(x-6) + 2y

A. Substitute x = -7 and y = 10 into the equation.

$3( - 7 - 6) + 2(10)$

Use the Distributive Property:

$- 21 - 18 + 20$

Solve:

$- 19$

B. Substitute x = 5 and y = -2 into the equation.

$3(5 - 6) + 2( - 2)$

Use the Distributive Property:

$15 - 18 + -4$

Solve:

$-7$

C. Substitute x = 0 and y = 6 into the equation.

$3(0 - 6) + 2(6)$

Use the Distributive Property:

$- 18 + 12$

Solve:

$-6$

D. Substitute x = 3 and y = 3 into the equation.

$3(3 - 6) + 2(3)$

Use the Distributive Property:

$9 - 18 + 6$

Solve:

$-3$

The table can be used to determine the solution of equations, 2x - 2y = 6 and 4x + 4y = 28.

NeTakaya

Answer:

(5, 2)

Step-by-step explanation:

Given the following system of equations;

2x - 2y = 6 ......equation 1.

4x + 4y = 28 ......equation 2.

To get an equivalent equation, we would multiply eqn 1 by 2;

2 * (2x - 2y = 6) = 4x - 4y = 12

The new equivalent system of equations are;

4x - 4y = 12

4x + 4y = 28

Adding the equivalent system of equations, we have;

(4x + 4x) + (-4y + 4y) = (12 + 28)

8x + 0 = 40

8x = 40

x = 40/8

x = 5

Next, we would find the value of y;

2x - 2y = 6

Substituting the value of x, we have;

2(5) - 2y = 6

10 - 2y = 6

Rearranging the equation (collecting like terms), we have;

2y = 10 - 6

2y = 4

y = 4/2

y = 2

Therefore, the solutions to the new system of equations are 5 and 2.

Check:

2x - 2y = 6

Substituting the values, we have;

2(5) - 2(2) = 6

10 - 4 = 6

6 = 6

What figure is a dilation of Figure A by a factor of 1/2 ?

lora16 [44]

A dilation of figure A by a factor of 1/2 is the last figure with sides 1in, 2 in, 0.5 in and 2.5 inch. Since dilation means becoming larger, smaller or wider from one figure, this is also same with similar figures where the ratios of corresponding sides should be the same. In this problem, the ratio is 0.5 or 1/2. Therefore figure A is similar to the last figure.
