Question

Which of the following is a solution of the inequality h + 9 <20?

A. 13
B. 12
c. 11
D. 10​

Answer 1

D. You subtract 9 from both sides and you have: h<11 . 10<11

Answer 2

D.10

Explanation:

if you just add the other numbers in place of variable h

13+9=22

12+9=21

11+9=20

10+9=19

only one addition problem adds up to a sum below 20 that being 10 so the answer is D
