Question

Your guinea pig is five inches more than half your snake's length. If your guinea pig is 47 inches how long is your snake?

Answer 1

guinea pig = S/2 + 5
47 = S/2 + 5
47 - 5 = 42
42 x 2 = 84 inches.
The snake is 84 inches.

Good Luck Studying :)

Answer 2

g = 1/2s + 5
g = 47

47 = 1/2s + 5
47 - 5 = 1/2s
42 = 1/2s
42 * 2 = s
84 = s.....so the snake is 84 inches
