Problem 3
<h3>Camille is correct</h3>
You subtract 4x from both sides, then divide both sides by -2 to fully isolate y.
===============================================
Problem 4
Multiply both sides by r to get
2mr = p-q
which is the same as
p-q = 2mr
The last step is to add q to both sides leading to this final answer
<h3>p = 2mr+q</h3>
================================================
Problem 5
Answer: ![r = \sqrt[3]{\frac{3V}{4\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B3V%7D%7B4%5Cpi%7D%7D)
This is the cube root of (3V)/(4pi)
----------------
Work Shown:
![V = \frac{4}{3}\pi r^3\\\\3V = 4\pi r^3\\\\4\pi r^3 = 3V\\\\r^3 = \frac{3V}{4\pi}\\\\r = \sqrt[3]{\frac{3V}{4\pi}}\\\\](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%5C%5C%5C%5C3V%20%3D%204%5Cpi%20r%5E3%5C%5C%5C%5C4%5Cpi%20r%5E3%20%3D%203V%5C%5C%5C%5Cr%5E3%20%3D%20%5Cfrac%7B3V%7D%7B4%5Cpi%7D%5C%5C%5C%5Cr%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B3V%7D%7B4%5Cpi%7D%7D%5C%5C%5C%5C)
Answer:
43
Step-by-step explanation:
3x - 17 and x - 9 are on a line together, so they add up to 180.
3x + 17 + x - 9 = 180
Then, you can solve the equation:
4x + 8 = 180
4x = 172
x = 43 degrees
Answer:
While factoring may not always be successful, the Quadratic Formula can always find the solution. The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
