X= the total questions
x×20%=16. 20%=0.2
so x×0.2=16
solve for x and that is your answer; )
We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.
Answer:
C. x > -1
Step-by-step explanation:
First you need to cancel out the -9 so you add 9 what you fo to one side you do to the other so -10+9 is -1 and you bring down the sign and you end up with x > -1
