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.
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
