Answer:
-9
Step-by-step explanation:
The triangle has two sides that are the same, so it is an isosceles triangle. Therefore, the base angles are the same.
Angles of a triangle add up to 180°, so:
70 + (x + 64) + (x + 64) = 180
70 + 2x + 128 = 180
2x = -18
x = -9
Answer: x=
1
Step-by-step explanation: solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
54.79 because if it's 4 and lower, you let them stay the same but if its five and above you let them go higher.

Answer: 8</h2>
Step-by-step explanation:
![10x+45 > 120\\10x+45-45 > 120-45\\10x > 75\\\frac{10x}{10} > \frac{75}{10} \\x > 7.5](https://tex.z-dn.net/?f=10x%2B45%20%3E%20120%5C%5C10x%2B45-45%20%3E%20120-45%5C%5C10x%20%3E%2075%5C%5C%5Cfrac%7B10x%7D%7B10%7D%20%3E%20%5Cfrac%7B75%7D%7B10%7D%20%5C%5Cx%20%3E%207.5)
Therefore, Mel has to work at least 7.5 hours or 8 total hours.
