Answer:

y = -3

Step-by-step explanation:

9x + 7y = -12

9(1) + 7y = -12

9 + 7y = -12

7y = -12 - 9

7y = -21 (divide both sides by 7)

y = -3

Answer:

y = -3

Step-by-step explanation:

9x + 7y = -12

Let x = 1

9 (1) + 7y = -12

9  + 7y = -12

Subtract 9 from each side

9 -9 + 7y = -12-9

7y = -21

Divide each side by 7

7y/7 = -21/7

y = -3

I need 50 gallons of milk replacer for calves and the powder mixture says it's 6.25 oz for 5 gallons how many oz of powder do I
zubka84 [21]

Answer:

62.5 oz

Step-by-step explanation:

We can use the ratio proportion method:

x:50::6.25:5

x = (50x6.25)/5

OR a more simple method is to do this:

5 gallons of milk require 6.25 oz. How many oz of powder do I need to get 10x that amount? Since 50 is 10x5, you do the same thing for 6.25, and get 62.5
