The Baker family and the Martin family each used their sprinklers last summer. The water output rate for the Baker family's sprinkler was 40L per hour. The water output rate for the Martin family's sprinkler was 35L per hour. The families used their sprinklers for a combined total of 60 hours, resulting in a total water output of 2200L. How long was each sprinkler used?

answer: 193

explanation:

200-7 = 193

i believe it's a.

i'm not sure on this one, most likely correct.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

-1   1/6.   you dont subtract the denominators
