Inverse means

Multiple Choice

Which of the following inverse operations is incorrect?

• inverse of addition is subtraction

• inverse of multiplication is division

• inverse of division is squaring

• inverse of multiplication is division

13 = z + 6

• subtract 6 from both sides

• z = 7

r - ( 2 ) = 15

• add 2 to both sides

• r = 17

Multiple Choice

How do we solve f - 12 = 4

• add -12 to both sides

• subtract 12 from both sides

• add 12 to both sides

• add 4 to both sides

16 = 4p

• divide both sides by 4

• p = 4

k/3 = -10

• multiply both sides by 3

• k = -30

Multiple Choice

How do we solve 2k = 100?

• multiply by 2 on both sides

• divide by 2 on both sides

• add 100 to both sides

• divide by -2 on both sides

Multiple Choice

7 + g = 11

• g = 4

• g = -4

• g = 18

• g = -18

Multiple Choice

z/4 = -8

• z = -32

• z = 32

• z = 2

• z = -2
