Algebraic Sentences 2 - Sample Math Practice Problems

The math problems below can be generated by MathScore.com, a math practice program for schools and individual families. References to complexity and mode refer to the overall difficulty of the problems as they appear in the main program. In the main program, all problems are automatically graded and the difficulty adapts dynamically based on performance. Answers to these sample questions appear at the bottom of the page. This page does not grade your responses.

Complexity=1, Mode=basic

Write an algebraic sentence using the given information. Use / for division.
Order your answer by magnitude. For example, write 2p + 4 instead of 4 + 2p
Use <= for ≤ and >= for ≥

1. Peter earns at least 8 dollars an hour.
Let p be what Peter earns hourly.

2. John earns at least 10 dollars an hour.
Let j be what John earns hourly.

Complexity=1, Mode=avg

Write an algebraic sentence using the given information. Use / for division.
Order your answer by magnitude. For example, write 2p + 4 instead of 4 + 2p
Use <= for ≤ and >= for ≥

1. One-tenth of a number ( f ) is at most -7.

2. You score 14, 20, and 27 points in your first 3 games.
Your goal is to have an average of at least 23 points per game.
Let z = number of points you score in the next game. Which inequality matches your goal?

Complexity=1, Mode=adv

Order your answer by magnitude. For example, write 2p + 4 instead of 4 + 2p
Use <= for ≤ and >= for ≥

1. Let a be the number of adults on a bus. What does 6(a + 10) represent? 16 more than the number of adults on a bus
6 times the number of adults on another bus that has 10 more adults
60 more than the number of adults on a bus
10 more than 6 times the number of adults on a bus

2. Express the following relationship as an algebraic sentence.
(Do not include dollar signs, $, in your answer.)

1	Let a be the number of adults on a bus. What does 6(a + 10) represent?	16 more than the number of adults on a bus 6 times the number of adults on another bus that has 10 more adults 60 more than the number of adults on a bus 10 more than 6 times the number of adults on a bus
Solution 16 more than the number of adults on a bus a + (6 + 10) 6 times the number of adults on another bus that has 10 more adults 6(a + 10) 60 more than the number of adults on a bus a + (6 × 10) 10 more than 6 times the number of adults on a bus 6a + 10

2	Express the following relationship as an algebraic sentence. (Do not include dollar signs, $, in your answer.) The cost of buying DVD's online is $10 per DVD plus $19 for shipping. You don't want your spending to exceed $55. Let z = number of DVD's you can purchase.
Solution To not exceed means to not go beyond, or mathematically, less than or equal to. To exceed means greater than.
