Answer:
7
Step-by-step explanation:
Remove parentheses.

Add −8 and 4.5.

Subtract 8.25 from 6.25.

Multiply 4 by −3.5.

Divide −14 by −2.
= 7
3/4x+5/6=5x-125/3
3/4x+5/6-5/6=5x-125/3-5/6
4/3x=5x-85/2
4/3x-5x=5x-5x-85/2
-17/4x=-85/2
(-4*-17/4x)=(-85/2*-4)
17x=170
x=170/17
x=10
Answer:
4
Step-by-step explanation:
It's going backwards by two
Answer:
x^2 + x^5 + C.
Step-by-step explanation:
∫2x + 5x^4 dx
= 2 * x^2/2 + 5 * x^5/5 + C
= x^2 + x^5 + C.
