Question

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

Answer 1

Answer:

length of foot = y

length of forearm = x = 17

Equation: y = 0.860x + 3.302

Plug in 17 for x in the equation, and simplify. Remember to follow PEMDAS, first multiply, then combine like terms:

y = (0.860)(17) + 3.302

y = 14.62 + 3.302

y = 17.922

length of foot = y = 17.922 inches long

Step-by-step explanation:

Answer 2

Plug 17 in for X. Then do PEMDAS. 0.860(17)= 14.62. Then 14.62+3.302= 17.922 in.
