I just happened to notice that 32 is incorrect, it should be A
33. (21x+14)/5y+4y*5y/7(3x+2)
((21x+14)*5y)/((9y*7(3x+2)
((5(21x+14)/63(3x+2)
35(3x+2)/63(3x+2)
5/9 is the answer
37. |-3--7|+|-7--3|
|-3+7|+|-7+3|
|4|+|-4|
4+4=8
8 is the correct answer
38. 99999/1 you can 99999
2^-2 x (13x3)-5^3
1/ (2^2) * 39 - 125
1/4 *39 -125
39/4 -125
9 3/4 - 125
factor out -1
- (125-9 3/4)
borrow to subtract the fraction
- (124 4/4 - 9 3/4)
- (115 1/4)
-115 1/4
The answer you are looking for is length × with
One yard is 0.0005 miles,
548 * 0.0005 = 0.274,
So the answer is 0.274 miles.
Hope this helps.
