Answer:
36/45 and 35/45
Step-by-step explanation:
5 and 9's least common denominator is 45 and to get to that you need to multiply both top and bottom of how to get to 45. How I got to 45 the easiest way is to keep multiplying both numbers until the reach the same product. In this case for 4/5, you multiply it by 9 for top and bottom. And for 7/9, it would be multiplying by 5 for top and bottom which will get you both of the answers. Hopefully this answers your question.

Answer:
the correct choice is marked: x = 11; Q = 55°
Step-by-step explanation:
If P and Q are supplementary, then ...
Q = 180° -P
Q = 180° -125°
Q = 55°
Then we have ...
5x = 55°
x = 11°
