Question

Which is a solution of the inequality?
p + 4 – 2(p – 10) > 0
A. 29

B. 26

C. 24

D. 22

Answer 1

i would go with c

Answer 2

i did c the last time and got it wrong

Answer 3

lets try simplifying
p + 4 – 2(p – 10) > 0
first distribute
p +4 -2p +20 > 0
combine like terms
-p+24 > 0
bring 24 to other side
-p > -24
divide by -1 (remember to flip the sign when dividing by negative!)
p < 24

Answer 4

i put c down the first time on the exam and they mark it as wrong

Answer 5

oh i see, it's not C because the solution says p <24, 24 is not < than 24
only D is less, tricky question!

Answer 6

ooh thanks
