Answer:
by folllowing the rules of pemdas we see that 2+2+9x8 is sovled as so:
2+2+9x8
2+2+72
4+72
76
Step-by-step explanation:
the answer would be 42.9 because the final answer (not rounded) would be 42.8888 however if you round the 8 you get 42.9
Answer:
12/12
Step-by-step explanation:
I would say simply perform the division already indicated.
(16 in)/(12 h) = 16/12 in/h = 4/3 in/h
__
Alternatively, divide the given rate by 1. The form 12/12 gives you the same thing as above:
(16 in)/(12 h)/(12/12) = (16/12) in/h = 4/3 in/h
The roots of 54 are: 1 and 54, 2 and 27, 3 and 18, 6 and 9, then it restarts all over again.
The two numbers have to multiply up to 54, and add up to 3. 9 and 6 have a difference of 3, and the multiplied sum is negative, so this is your pair.
9 and -6 fit this criteria, since they add up to 3 and multiply to 64.
