I'll give you a hint. <u><em>This questions is about order of operations for pemdas. Its stand for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add and s-subtract that came from left to right.</em></u>
First you had to calculate with exponents first.
Then you multiply and divide from left to right.
Final answer: 
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.

Answer:
6) f=45
7) r=57
Step-by-step explanation:
the angles of a triangle will always add up to 180 degrees. Therefore, for the first one the three inside angles have to be 30, 15, and 135. If 135 is the supplementary angle to f, 45 must be the degree of f.
Same idea for the second one. 180-143=37. so 37+86+r=180. solve for r to get 57.
The total number of hoagies sold can be figured out by working out the sum of the Italian hoagies and the roast beef hoagies.
The sum is 42 + 53 = 95 total hoagies.
Now you just create a ratio of Italian hoagies to the total number of hoagies, which is:
42:95 (Italian:Total)
