Joe's age x, is 5 times his age 10 years ago. Which equation represents the statement?

a) x = 5x - 6
b) x = 5x + 6
c) x= 5 - 10x
d) x = 5(x - 10)

Answer 1

The answer is d) x=5(x-10)

Answer 2

d) X=5(X-10)

Explanation:

Joe's age is change to X, so we know that his age today is 5 times his age 10 years ago.

His age ten years ago is X-10, if for example he is 25 today then his age ten years ago would be 15 (25-10).

If his age now is 5 times his age 10 years ago we will have to multiply his age ten years ago to get his age today.

Example:

5(X-10), this is how we can write 5 times his age 10 years ago, in a mathematical way.

Now we just have to know that this equation is equal to his age today X.

5(X-10) = X, or another way to put it is:

X=5(X-10)
