What is the solution to the inequality 100 + a < 43 + 92 when a = 32?

Back

True, because 100 + 32 < 135.

Front

What is the solution to the inequality 16 > t + 12 when t = 3?

Back

True, because 16 > 3 + 12.

Front

What is the value of a when a = 6 and you calculate a x 42?

Back

252, because 6 x 42 = 252.

Front

If n = 5, what is the value of n + 23 and 23 + n?

Back

Both expressions equal 28, so they are the same.

Front

What does the equation a ÷ 3 = 20 - 1 mean when a = 57?

Back

True, because 57 ÷ 3 = 19, which equals 20 - 1.

Front

What is the purpose of solving inequalities?

Back

To find the range of values that satisfy the condition of the inequality.

Front

What is a variable in algebra?

Back

A variable is a symbol, often a letter, that represents an unknown value.
