I'm having problem trying to solve this question. Solve for x,8 is to 64 as 2 is to x, I need to know if this is the best answer (x-1)^2=64 (9-1)^2=64 (8)^2=64, is 64 the right answer yes or no.

Question

I'm having problem trying to solve this question. Solve for x,8 is to 64 as 2 is to x, I need to know if this is the best answer (x-1)^2=64 (9-1)^2=64 (8)^2=64, is 64 the right answer yes or no.

Answer 1

Answer 2

8/64 = 2/x

multiply both sides by 64 x

8 x = 128
x = 16

Answer 3

To solve this problem, we can use the concept of proportions.

The given statement is: 8 is to 64 as 2 is to x. We can write this as the proportion:

8/64 = 2/x

To solve for x, we can cross multiply:

8x = 64 * 2

Simplifying the equation:

8x = 128

To isolate x, divide both sides of the equation by 8:

x = 128/8

Simplifying further:

x = 16

So, the value of x is 16, not 64. Therefore, (x-1)^2 = 16^2 = 256, not 64.
