X=1 so it is 1×1×1=1 so.... it is 19+1
Answer:
20%
Step-by-step explanation:
4/5=.80
1-.80=.20
.20=20%
Yes, I can solve that inequality.
Any value of ' r ' that's less than 1/3 is a solution.
Let the speed of the current equal c
and the speed of the boat in still water equal b.
b + c = 1.5 (b - c)
b + c = 1.5b - 1.5c
0.5b = 2.5c
b = 5c
The speed of the current is 1.5 mph so
b = 5 * 1.5 = 7.5 mph
