Answer:
175lb
Step-by-step explanation:
Let's say 100% - original weight
and 12% - 21lb
weight = (100*21)/12=175lb
Width: x
length: x + 4
Equation: 2(x + x + 4) = 56
2(2x + 4) = 56
4x + 8 = 56
4x = 48, x = 12
Width = 12, 12 + 4 = length
Solution: the length is 16 inch
Answer:
The equation i came up with is $55= 7.8x - 47.20
The answer to number 3 is -12 because you would do X times 4 and then add 8
the answer to number 4 is 46 because you would do X times 3 and then add 7
650/300 = 2(1/6)
(1/6) of 1 hour = 10mins
The flight took 2hr and 10mins.
