Answer:
a)27-x
b)27+x
Step-by-step explanation:
when a boat travels in the same direction as the current is downstream-->speeds the boat. If the rate of the boat in still water is 27 mph and the rate of the current of a river is x mph, the rate of the boat when the boat is going downstream is 27+x
when a boat travels against the current is upstream-->slow down. If the rate of the boat in still water is 27 mph and the rate of the current of a river is x mph, the rate of the boat when the boat is going upstream is 27-x
Answer:
a=-13
Step-by-step explanation:
16−5a+2a−1=41−a
16-1-41 = 5a-2a-a
-26 = 2a
a= -26/2
a=-13
I = prt
420 = 7000 x .02 x t
420 = 140 x t
420/140 = 140 x t /140
t = 3 years
Each step subtracts 3 from the previous number.
14 - 3 = 11
11 - 3 = 8
The sequence will continue:
8 - 3 = 5
5 - 3 = 2
2 - 3 = -1
Etc.
14, 11, 8, 5, 2, -1...
You would multiply 29.50 x 0.07 which would give you 2.065. The tax amount would be $2.07. The total after tax would be $31.57
