10 + 3(5n - 12) = 13n
10 + 15n - 36 = 13n
15n - 13n = 36 - 10
2n = 26
n = 13 [Answer C]

10+3(5n-12)=13n
Distribute:
10+15n-36=13n
Add like terms:
-26+15n=13n
Subtract 15 on both sides:
-26=-2n
Divide by -2 on both sides:
13=n (c)
Hope it helps!

If u(x) = x^5 – x^4 + x^2 and v(x) = –x^2, which expression is equivalent to (u/v)(x)?
Effectus [21]
Hello: 
x^5 – x^4 + x^2 =x^2(x^3 - x^2 +1)
(u/v)(x)= x^2(x^3 - x^2 +1)/(-x^2)
(u/v)(x)= - (x^3 - x^2 +1) = -x^3+x^2-1    (  x :  no zero)
