Plz me? its going to take me awhile and the rest of my no-school !

1/3 + 1/5 =

5/15 + 3/15 = 8/15

1/3          x

 =

8 /15     16

cross products

1/3 * 16 = 8 /15 x

multiply by 15/8

1/3 * 16 * 15/8=x

10 =x

She needs 10 cups of flour

1/5          x

 =

8 /15     16

cross products

1/5 * 16 = 8 /15 x

multiply by 15/8

1/5 * 16 * 15/8=x

6 =x

She needs 6 coups of sugar

Choice D

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
