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
Area=L*W*H so try that maybe that will work
First you distribute
17(a) - 17(15) = 153
then solve what you can
17(a) - 255 = 153
then add to cancel out the subtraction
17(a) - 225 = 153
+225 +225
17(a) = 378
then divide
17(a) = 378
/17 /17
a= 22.2352941
a= 22.2
100=-2x+40
100-40=-2x
isolate the variable by subtracting 40 from both sides
60=-2x
divide 60 by -2
-30=x
