serious [3.7K]3 years ago
8 0

Solve equation [1] for the variable x [1] x=(3y+6)

Plug this in or variable x in equation [2]

[2] 2(-3y+6)-y= 10

[2] -7y=-2  

// solve equation [2] for the variable y

[2]   7y= 2

[2]    y=2/7

By now we know this much  

X= -3y+6

Y=2/7

Use the y value to solve for x  

X=-3(2/7)+6=36/7

(x,y)=(36,7), (2/7)

Hank and Debra each own two milking cows. One day, they milked their cows and compared the amount of milk the cows produced in t
drek231 [11]

Answer:

The answer to your question is  2 7/24

Step-by-step explanation:

Data

Hank's cows = 4 3/4   and  4  1/8

Debra's cows = 5 1/2  and  5 2/3

Process

1.- Convert the mixed functions to improper fractions

Hank's           (16 + 3)/4  = 19/4           (32 + 1)/8 = 33/8

Debra's          (10 + 1)/2 = 11/2              (15 + 2)/3 = 17/3

2.- Sum up Hank's milk and Debra's milk

Hank's       19/4 + 33/8 = 38/8 + 33/8 = 71/8

Debra's      11/2 + 17/3 = 33/6 + 34/6 = 67/6

3.- Subtract Hank's milk to Debra's milk

                 67/6 - 71/8 = (268 - 213)/24

                                    = 55/24

-Convert into a mixed fraction

                                2

                      24   55

                                7

                                      55/24 = 2 7/24

4.- Conclusion

Debra milked 2 7/24 more milk than Hank
