2(q-10)
OpenStudy (ryanwhite499):
Hmmmm... hold on
OpenStudy (anonymous):
i see now it is B 10(q-20)
OpenStudy (ryanwhite499):
Yes ...
OpenStudy (ryanwhite499):
Oh yes that is correct 10q-20=0
10q=20
q=20/10=2

10(q-20)
If you distribute the 10, will you get the original?
OpenStudy (anonymous):
what about this math problem:
Simplify and determine the coefficient of (negative 2/3x)(3y)(-2x)
OpenStudy (anonymous):
@Worior9131 for your original problem, did you check the distribution to make sure it worked?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
really? cuz 10*20 = 200

the other person said i was correct
OpenStudy (anonymous):
the other person was solving an equation.
Your problem isn't an equation. It's asking you to factor/reverse distribute
OpenStudy (anonymous):
it is asking for the equivalent not what is = to 20
OpenStudy (anonymous):
equivalent means equal, so it has to equal 10q + 20 when you distribute
OpenStudy (ryanwhite499):
@peachpi she is talking about this problem. What are you talking about?

He answered that correctly. He said it was B
OpenStudy (ryanwhite499):
Its correct
OpenStudy (anonymous):
you guys kill me stressing out about the options. LEARN THE MATH, and then you'll be able to see the correct option, which isn't B
