5 0

Answer:

2.5

Step-by-step explanation:

<em>Let x be the number of hours both people baby sit and y be the number of hours that they each earn. </em>

<u>Sarah: </u>

y = 10 + 2.5x

<u>Carly: </u>

y = 7.5 + 3.5x

<em>You know that the number of hours should be the same (y). </em>

10 + 2.5x = 7.5 + 3.5x

<em>Evaluate and find x. </em>

10 - 7.5 = 3.5x - 2.5x

x = 2.5

soybean meal is 16% protein; cornmeal is 8% protein. how many pounds of each should be mixed together in order to get 320-lb mix
nlexa [21]

Answer:

120 lb of soybean meal

200 lb of cornmeal

Step-by-step explanation:

S = pounds of soybean meal

C = pounds of cornmeal

S + C = 320  →  C = 320 – S

0.16S + 0.08C = 0.11 × 320 = 35.2

16S + 8C = 3520

16S + 8(320 – S) = 3520

16S + 2560 – 8S = 3520

8S + 2560 = 3520

8S = 960

S = 120

C = 320 – 120 = 200
