Answer:
161
Step-by-step explanation:
the sum of the two interior angles equals that exterior angle
121+40=161
5x+29 = 45
5x = 16 (subtract 29 from both sides)
x = 16/5.
That is the answer, I don't know where you got the value of 5 but it doesn't make sense. To prove it, let's try put it into the equation:
5x5 + 29 =45
25 + 29 = 45
Wrong! 25 + 29 = 54.
If "4/2/7" is all we have to work with, then PEMDAS rules will save the day. Do the division from left to right.
4/2 becomes 2. Then we have 2/7, a proper fraction. I don't see where an improper fraction would come from in this case.

Answer: she still has to cut off 19/16 inches.
Step-by-step explanation:
Olivia wants to cut 3 3/4 inches from a piece of string. Converting 3 3/4 inches to improper fraction, it becomes 15/4 inches.
She has already cut off 2 9/16 inches from the piece of string. Converting 2 9/16 inches to improper fraction, it becomes 41/16 inches.
Therefore, the length of string that is left for her to cut off would be
15/4 - 41/16 = (60 - 41)/16
= 19/16 inches
