Review: Expressions, Equations, Inequalities

Front

What is the solution to the equation 17 = x + 3?

Back

x = 14

Front

What does the Commutative Property of Addition state?

Back

The order of addition does not change the sum, e.g., a + b = b + a.

Front

How do you solve the inequality r - 14 ≥ 17?

Back

Add 14 to both sides to get r ≥ 31.

Front

What equation represents the situation: Robyn had some video games then bought 4 more, now she has a total of 10 games?

Back

v + 4 = 10.

Front

What is the Associative Property of Addition?

Back

The way in which numbers are grouped does not change their sum, e.g., (a + b) + c = a + (b + c).

Front

What is an equivalent expression for 7 + (8 + 9) using the associative property?

Back

(7 + 8) + 9.

Front

What is the first step in solving the equation x + 5 = 12?

Back

Subtract 5 from both sides to isolate x.

Front

What is the definition of an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater than or less than another.

Front

How do you solve the equation 2x + 3 = 11?

Back

Subtract 3 from both sides to get 2x = 8, then divide by 2 to find x = 4.
