Question

Four times the sum of a number and 15 is at least 120. Let x represent the number. Find all possible values for x.

A. x ³ 26

B. x ³ –15

C. x ³ 15

D. x ³ –26

Answer 1

let x be the number

the sum of the number and 15 is x + 15

4 times the sum of the number and 15 is 4(x + 15)


4 times the sum of a number and 15 is at least 120

this uses an inequality

\[4(x + 15) \ge 120\]

all you need to do is solve for x
