Question

Hello you beautiful and amazing person, i need help with some Pre-Algebra stuff. Its fairly easy, here is the problem-

The equation below can be used to find the length of a foot or forearm when you know one or the other.

(length of the foot) = 0.860 • (length of the forearm) + 3.302

If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.

Using this equation, how long would the foot of a person be if his forearm was 17 inches long?

Thats all, thanks for your help :) OH and its worth 50 points and if you take them i will NOT hesitate tp report you.

Answer 1

You would plug in 17 for x.
Y=.860(17)+3.302
Y=17.922
17.922 is the length of the foot
Check work by finding x
17.922=0.860(x)+3.302
X=17
Which is the length of the forearm
