Which is a solution of the inequality? p + 4 – 2(p – 10) > 0 A. 29 B. 26 C. 24 D. 22

OpenStudy (anonymous):

im not sure what do do on this question at all

OpenStudy (anonymous):

to*

OpenStudy (campbell_st):

I'd just substitute each evaluate to find the one greater > 0

OpenStudy (campbell_st):

it can be solved... if needed

OpenStudy (anonymous):

i have no i idea how to do that

OpenStudy (campbell_st):

ok... can you distribute -2(p - 10)..... what do you get

OpenStudy (anonymous):

-2p + 20?

OpenStudy (campbell_st):

correct so looking at the whole problem you have p + 4 -2p + 20 > 0 can you collect the like terms..

OpenStudy (anonymous):

say what lol

OpenStudy (anonymous):

4 -3p + 20> 0?

OpenStudy (campbell_st):

not quite, it p - 2p + 4 + 20 > 0 or -p + 24 > 0 does that make sense?

OpenStudy (anonymous):

-3p + 20 > 0?

OpenStudy (anonymous):

24*

OpenStudy (campbell_st):

can you see how I got - p?

OpenStudy (anonymous):

im lost

OpenStudy (campbell_st):

ok... so looking at the terms in p what is 1 - 2 =

OpenStudy (anonymous):

- p + 24 > 0 isnt an answer

OpenStudy (campbell_st):

thats ok.... so to get all the possible answers subtract 24 from both sides - p + 24 > 0 - 24 -24 --------------- -p > -24 is that ok..?

OpenStudy (anonymous):

now im even more confused sorry

OpenStudy (campbell_st):

this is like solving an equation but instead of an equals sign, you have >

OpenStudy (anonymous):

-24 isnt an anwer

OpenStudy (anonymous):

answer*

OpenStudy (campbell_st):

ok... last step multiply both sides of the inequation by -1 which will reverse the inequality sign p < 24 find a number in you list that is less than 24 thats the answer..
