Answer:
-5
Step-by-step explanation:
First, distribute the 2 to the 3, -9, and 5. You will get 6 + 6 - 18 + 10 + (-9). Then, you can start from the beginning and work through combining the terms. The original equation is in bold after every step.
6 + 6 - 18 + 10 + (-9)
6+6 = 12
12 - 18 + 10 + (-9)
12-18 = -6
- 6 + 10 + (-9)
-6 + 10 = 4
4 + (-9)
4 - 9 = -5

Answer:
Arc KL 
Arc OM 
Step-by-step explanation:
We know that Angle NPM is equal to 90 degrees.
Therefore, Angle KPM is also equal to 90 degrees.
We are told that Arc LM is equal to 67.
Thus, the measure for Arc KL is equal to 
We also know that Angle OPN is equal to Angle KPL.
Therefore, the measure of Arc ON
Using that information, we know that Arc OM is equal to

The freezing point for antifreeze is -67 F or -55 C
Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
