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?

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:

If the forearm of a person is 17 inches long then his foot would be 17.922 inches long.

What is an equation?

"It is a mathematical statement which consists of equal symbol between two algebraic expressions."

For given question,

We have been given an equation y = 0.860x + 3.302

y = length of the foot and x = length of the forearm

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

We need to find the foot of a person be if his forearm was 17 inches long.

For x = 17 inches, we need to find the value of y.

Substitute x = 17 in the given equation.

⇒ y = 0.860x + 3.302

⇒ y = 0.860 (17) + 3.302

⇒ y = 14.62 + 3.302

⇒ y = 17.922

Therefore, if the forearm of a person is 17 inches long then his foot would be 17.922 inches long.
