Question

Translate the sentence into an inequality. Two times the sum of a number and 18 is at least 15.Use the variable y for the unknown number.

Answer 1

2(y + 18) ≥ 15

Step-by-step explanation:

Let's explain each part of the sentence:

Two times means that we need to multiply by 2

The sum of a number and 18 can be represented as y + 18 because y is the unknown number

At least 15 means minimum 15 or greater than or equal to 15, so it is represented with the symbol ≥

Therefore, the complete sentence is represented by the following inequality:

2(y + 18) ≥ 15
