3-(2x-5)=-4(x+2)
We simplify the equation to the form, which is simple to understand
3-(2x-5)=-4(x+2)
Remove unnecessary parentheses
3-2x+5=-4*(x+2)
Reorder the terms in parentheses
3-2x+5=+(-4x-8)
Remove unnecessary parentheses
+3-2x+5=-4x-8
We move all terms containing x to the left and all other terms to the right.
-2x+4x=-8-3-5
We simplify left and right side of the equation.
+2x=-16
We divide both sides of the equation by 2 to get x.
x=-8
To convert a fraction to a decimal, divide the numerator by the denominator (divide the top by the bottom)
Number 28 would be y= -52x+148
I think your answer would be 4,000
Answer:
4/3
Step-by-step explanation:
If the ratio between the volumes of the first and the second cube is 64, the ratio between the sides is the cubic root of the ratio between the volumes, so:

![s1 / s2 = \sqrt[3]{64} = 4](https://tex.z-dn.net/?f=s1%20%2F%20s2%20%3D%20%5Csqrt%5B3%5D%7B64%7D%20%20%3D%204)
Doing the same for the second and third cubes, we have:

![s2/ s3 = \sqrt[3]{1/27} = 1/3](https://tex.z-dn.net/?f=s2%2F%20s3%20%3D%20%5Csqrt%5B3%5D%7B1%2F27%7D%20%20%3D%201%2F3)
So the ratio of the first cube side and the third cube side is:
