Answer:
x = 20°
Step-by-step explanation:
The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.
3x + 2x simplifies to 5x. 5x must equal 100.
100/5 = 20.
Therefore x = 20.
Reflecting a function across the x-axis means to change the sign of the function itself: you're mapping 
So, if you have a x/y values table, you simply have to change sign to all the values in the y column.
Answer: There are 8 students at Hamilton Middle School with red hair.
Step-by-step explanation:
Given: The proportion of the students at Hamilton Middle School have red hair = 2% = 0.02
Total students in Hamilton Middle School = 400
Then , the number of students have red hair = (proportion of the students have red hair ) x (Total students )
= (0.02) x (400)
= 8
Hence, there are 8 students at Hamilton Middle School with red hair.
