Question

1. Evaluate 3y - 4 for y =5

2. 65 + x = 99 x = ?
3. Find the product. 38.7 *21
4. Which value satisfies the equation? 9x + 3 = 30 *
-2
-3
-4

Answer 1

1. Evaluate 3y - 4 for y =5

3*(5)-4=15-4=11

2. 65 + x = 99 x = ?

65+x=99

x=99-65

x=34

3. Find the product. 38.7 *21

38.7*21=812.7

4. Which value satisfies the equation? 9x + 3 = 30

The right value for x would be:

9x+3=30

9x=30-3

9x=27

x=27/9=3
