Answer:
C, 40
Step-by-step explanation:
You can set up the equation as 20+4x=180
180 is the total angle of the line
4x=160 and divide each side by 4
x=40
Which value of x and y when plugged into the equation will create the same value on both sides?
The best way to do this is by trial and error.
Let's try x = 3 and y = 14.
y = 2x + 8
14 = 2(3) + 8
14 = 6 + 8
14 = 14
We got the same answer on both sides.
Answer: Choice D(3, 14)
Understand?
37 is a prime number which means it is only divisible by 1 and 37, therefore the only number that can go into 37 and 100 is 1.
