The sum of a number times 6 and 18 is at least 30.

Answer 1

Let X = the number

6X+18>30 6 times the number + 18 is at least 30

6X>30-18 subtract 18 from both sides

6X>12 divide both sides by 6

X>12/6 12 divided by 6 = 2

X>2

X is at least 2. That means the same as X is greater than or equal to 2.
