Question

Which is a solution of the inequality?
p + 4 – 2(p – 10) > 0

A. 29

B. 26

C. 24

D. 22

Answer 1

\[p+4-2(p-10)>0\]\[p+4-2p+20>0\]\[p-2p+4+20>0\]\[-p+24>0\]\[-p+24-24>0-24\]\[-p >-24\]\[p >24\]
the answer is C

Answer 2

Thank you!

Answer 3

u're welcome

Answer 4

-p > -24
When we multiply both sides by -1 the inequality sign must be reversed.
p < 24
Therefore D. 22 is the only correct solution.
