Answer:
I believe it is D.
Step-by-step explanation:
The associative property switches around the order of the digits to make the problem easier. In my opinion it is easiest to multiply the fractions together, and then the whole number.
If their mean is 5, then the numbers add up to 25.
Here are a few sets that do the job:
1, 2, 3, 4, 15
10, 20, 30, 40, -75
+2, -2, +99, -99, 25
1, 5, 5, 5, 9
Your answer would be A, B, and C.
Step-by-step explanation:
1) 51
2)32
3) 18
4)9
5)12
U estimate 46.78 to 47 and 18.55 to 19, so 47-19 is 28.
