On a particular day, the wind added 4 miles per hour to jaime's rate when she was rowing with the wind and subtracted 4 miles per hour from her rate on her return trip
jaime found that in the same amount of time she could row 57 miles with the wind, she could go only 33 miles against the wind.
what is her normal rowing speed with no wind?

15 miles per hour.

Step-by-step explanation:

Let x be her speed with no wind.

speed = distance / time.

With the wind:

x + 4 = 57 / t

t(x + 4) = 57

t = 57 / (x + 4)

Against the wind:

x - 4 = 33 / t

t = 33 / (x - 4)

Eliminating t from the 2 equations in bold we have:

57 / (x + 4)  = 33 / (x - 4)

57(x - 4) = 33(x + 4)

57x - 228 = 33x + 132

24x = 360

x = 360/24

x = 15 miles per hour.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
