Answer:
Step-by-step explanation:
(-12+50)/(-2-3)+72/(4+2)
simplify: 38/67/6
multiply by the reciprocal: 38/67*6/1
you get: 228/67
decimal: 3.402985075
Answer: (x-2) = (x+11)
------- -------
3 4
Step-by-step explanation:
First part is x-2 divided by on third. So the x-2 acts a the 1 so you put x-2 over 3. And you get:
(x-2)
--------
3
For the other side of the equation it is x +11 divide by 1/4. So the x+11 will act a the 1 in the fraction. And you will get:
(x+11)
--------
4
Answer:
(-36 x^3)/25
Step-by-step explanation:
Simplify the following:
(-4×9 x^2 x)/(5×5)
Combine powers. (9 x (-4) x^2)/(5×5) = (9 x^(2 + 1) 4 (-1))/(5×5):
-(9×4 x^(2 + 1))/(5×5)
2 + 1 = 3:
((-9×4 x^3)/5)/5
9 (-4) = -36:
(-36 x^3)/(5×5)
5×5 = 25:
Answer: (-36 x^3)/25
