Answer:

Jerry  is correct

Step-by-step explanation:

8^{x} = 512

this equation is asking 8 to what power is 512

Emma said the solution is x=3. Her explanation is 8 x 3 which would equal 24. This is not the correct answer.

Jerry's solution  is x = 3. His explanation is 8 x 8 x 8 which would equal 512. This is the correct answer.

Mel's solution is x = 8. Her explanation is 8 x 3 which equals 24. This is not the correct answer.

Victoria's solution is x = 8. Her explanation is 8 x 8 x 8 which would equal 512. However, her explanation is correct, her solution is not. 8^{8} = 16777216. That is what her solution is saying.

Answer:

C) 75 + 50x = 25 + 70x

Step-by-step explanation:

ABC Tech:

$50 an hour. So,for x hours= 50 * x = 50x

Service charge = 75 + 50x

Tech Squad:

$70 an hour. So,for x hours= 70 * x = 70x

Service charge = 25 + 70x

C) 75 + 50x = 25 + 70x

50x - 70x = 25 - 75

-20x = -50

x = -50/-20

x =5/2 = 2\frac{1}{2}hours
