Exercise 34 Page 410

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

3.25

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.

3y + 2x

y= 3/4, x= 1/2

3 * 3/4 + 2* 1/2

MoveLeftFacToNum

a*b/c= a* b/c

9/4 + 2 * 1/2
