Question

Which values are solutions to 90 < –30p + 15? Check all that apply.
p = –10
p = 0
p = –2.5
p = 3
p = –5
p = 7.6

Answer 1

Answer:

p = -10 and p = -5

Step-by-step explanation:

Given inequality,

$90 < -30 p + 15$

Subtract -15 on both sides of inequality,

$90 - 15 < -30 p$

$75 < -30 p$

Divide both sides of inequality by 30

$2.5<-p$

$2.5>p$   ( a < b ⇒ -a > -b )

$-2.5>p$

Hence, p must be less than -2.5

So, the possible value of p from the given options are,

p = -10 and p = -5.
