Question

Evaluate and match each expression on the left to its valueon the right, when x = 7 and y = 4.

Answer 1

Given: x = 7, y = 4. Evaluate the following expressions:

12 + x = 12 + 7 = 19

12 + x matches with 19

3x + y = 3*7 + 4 = 21 + 4 = 25

3x + y matches with 25

4y - 10 = 4*4 - 10 = 16 - 10 = 6

4y - 10 matches with 6

`(1)/(2)xy=(1)/(2)*7*4=14`

The last expression matches with 14
