Question

*The sum of 5
and the twice a
number is at
most 27*

Answer 1

x
`\leq` 11

Explanation:

The phrase "at most" is telling us that we have an inequality where the answer will be less than or equal to 27. If we let x be our missing number:

2x + 5
`\leq` 27

2x
`\leq` 22

x
`\leq` 11

Answer 2

Well i think that is true. and the mystery number i believe is 11

Explanation:

Well, first subtract 5 from 27, you get 22. Then divide that by two (because that is half). And you get 11.

11 · 11 = 22

22 + 5 = 27

Really hope this helps!
