Exercise 31 Page 410

Substitute 12 for x and 34 for y in the expression.

-0.25

Practice makes perfect

To evaluate the given expression for x = 12 and y = 34, we should substitute these values into the expression and simplify as much as possible.

x - y

x= 1/2, y= 3/4

1/2 - 3/4

a/b=a * 2/b * 2

2/4 - 3/4
