Answer:

Step-by-step explanation:
-This is an LCM problem.
-To simplify, we introduce a least common multiplier which is equivalent the product of the denominators:

#We introduce the LCM and adjust the fractions based on it :

Hence, the simplified form of the fraction is: 
Answer:
13 months
Step-by-step explanation:
m=number of months
30(m)+50
30*13= 390
390+50=440
Answer:
2/-3
Step-by-step explanation:
Hope this helped. And I know that you can choose more than one, but I'm pretty sure this is the only one that's equivalent to -2/3
Answer:
Step-by-step explanation:
This triangle is a polygon. By definition, all the exterior angles of ANY polygon add up to equal 360 degrees. So we add up all the exterior angles and solve for x. That's the first step.
7x - 2 + 9x - 31 + 4x + 33 = 360
Combining like terms gives us
20x + 0 = 360 or simply
20x = 360 so
x = 18
In order to find the value of the angle exterior to angle C, we sub 18 in for x:
7(18) - 2 = 124
