Answer:
Step-by-step explanation:
The given equation is ![\sqrt[3]{x+8}=-4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B8%7D%3D-4)
.
We cube both sides of this equation to obtain;
![(\sqrt[3]{x+8})^3=(-4)^3](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%2B8%7D%29%5E3%3D%28-4%29%5E3)
.
This implies that;
We group similar terms to obtain;
We simplify the right hand side of the equation to obtain;
Therefore x=-72 is the solution of the given equation.
I think the answer would me -$470,000,000
Answer:
the order is important when you are performing a composite transformation
OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
Hope this helps

-5 + 9 = 4
-5 - 9 = -14
4 and -14 are both 9 units from -5 on a number line
