Answer:
Option A
Annette picked 50 roses from the garden
Step-by-step explanation:
Let us understand the problem, designating letters to represent unknown quantities.
Let the total number of roses = x
20% of the roses were red means that 20% of x = red
Since the number of red roses = 10,
we will have that 20% of x = 10
mathematically, we will have

hence, Annette picked 50 roses from the garden
Step-by-step explanation:
(-7)+(-6)+(-1)=-14
(-14)-3=-11
-11÷7=-1.5714285714286 or -2 if you round too the tenths place

Answer:
rate of the current = 2 mph
Step-by-step explanation:
d = rt
Let c = rate of the current
Rate going downstream = c + 40
Time going downstream = 126/(40 + c)
Rate going up stream = 40 - c
Time going upstream = 114/(40 - c)
Since the times are equal, then
126/(40 + c) = 114/(40 - c)
126(40 - c) = 114(40 + c)
5040 - 126c = 4560 + 114c
240c = 480
c = 2 mph
