Question

Translate the sentence into an inequality.The sum of a number times 7 and 21 is at most 30.Use the variable b for the unknown number.Thank

Answer 1

The number is 7, number times would be 7b with the variable

the sum 7b and 21 = 7b + 2

at most ≤ 30, is at most 30 means that the most the value is allowed to be is 30

So the complete inequality is 7b + 2 ≤ 30
