Cecile packages snack mix at a health food store. she uses 1/3 of her supply of sunflower seeds to make a salted snack mix and 2/9 of her supply to make an unsalted snack mix. if cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?

The number of the pounds of seeds that are in her supply is 18 pounds of seed.

Let the number of the pounds of seeds that are in her supply be represented by x.

Based on the information given, the calculation will go thus:

1/3x + 2/9x = 10

5/9x = 10

Cross multiply

5x = 9 × 10

5x = 90

x = 90/5.

x = 18

Therefore, the number of the pounds of seeds that are in her supply is 18 pounds of seed.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
