Two angles are complementary if the sum of their measures is 90⁰. <P and <Q are complementary. The measure of <P is 61⁰. Write and solve an equation to find the measure of <Q.

• 61 + 90 = Q; 151

• 61 + Q = 90; 29

• Q + 90 = 61; -29

• 61 + q = 90; 39

A gardener measures the tallest of his prize-winning sunflowers and finds that the height is 60 in. The sunflower was 52 in. tall the last time the gardener measured it. Write and solve an equation to find how many inches the sunflower grew.

• g + 60 = 52; g = -8

• g - 52 = 60; g = 112

• g + 52 = 60; g = 8

• g - 60 = 52; g = 112

Sirus wrote a check for $67. He subtracted that amount from his account balance and found that the balance was $329 after writing the check. Write and solve an equation to find his balance before writing the check.

• x + 67 = 329, x = $262

• 67 - x = 329, x = $262

• x = 329 - 67, x = $262

• x - 67 = 329, x = $262
