3/2x+1/3=10 5/6 what does x equal to

x = 7

Step-by-step explanation:

So we have:

In order to make this simpler, we have to make each fraction have a common denominator. Since 2*3=6, let's have 6 be that denominator. Here's what we do for the three fractions:

Putting those back into our equations, we have:

We must isolate the x on one side and solve for it by combining like terms:

Our answer is x = 7.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
