ACC Writing, Evaluating, and Simplifying Algebraic Expressions

Write an algebraic expression that represents the situation: A water bottle contains 16.9 oz. Each minute, 3.5 oz. of water is consumed. How much water is left in the bottle after m minutes?

• 16.9m - 3.5

• 16.9(m - 3.5)

• 16.9 - 3.5m

• 3.5m - 16.9

Write an algebraic expression that could represent the phrase "four more than twice the product of eleven times a number of animals, a".

• 2(11a + 4)

• 2(11a) + 4

• 4 + 11a²

• 4 + 11a + 2

Write an expression that represents the height of a tree that begins at 8 feet and increases by 2 feet per year. Let y represent the number of years.

• 8 + 2y

• 8 ÷ 2 + y

• 8 + 2 - y

• 8 - 2y

Write an expression that can represent the phrase “a number cubed into six”.

• 6 ÷ n²

• n³ ÷ 6

• 6 ÷ n³

• n² ÷ 6

State the number of terms in each expression: 21 ÷ a − 8c + 14b • 26

State the number of terms in each expression: 10xyz ÷ 1.87t • 6

Evaluate the expression −10 − 2d given d = −5.

Evaluate the expression −32 ÷ f² given f = −4.

Evaluate the expression fe ÷ d + 2 given d = −5, e = 10, f = −4.

Write an expression for the following situation, then solve using the given values: Emelia earns $8.74 per hour plus a gas allowance of $3.50 per day at her job. Write an expression that represents the total Emelia’s job will pay in a day when she works.

• 8.74h + 3.50

• 3.50h + 8.74

• 3.50 + h + 8.74

• 8.74 - 3.50h
