answer:
q = 75
step-by-step explanation:
- we can set up an proportion for this
when p = 4, q = 30
- put this as a proportion so that this is one side
- look at what i did
4 / 30 = 10 / x
4x = 300
x = 75
- here i used x as q, therefore whatever x is, will be q
q = 75
15+10
i believe this is right
5y-5y^2-5+2+2y+3y^2-1
collect like terms
7y-2y^2-4
reorder the terms
-2y^2+7y-4
-2y^2+7y-4 is your final answer, I hope this helps!
