Answer:

x = 27

Step-by-step explanation:

3x-4y = 65

Let y = 4

3x - 4*4 = 65

3x -16 = 65

Add 16 to each side

3x-16+16 = 65+16

3x  = 81

Divide each side by 3

3x/3 = 81/3

x = 27

Kenneth earns $450 for working 37 1/2 hours. If Kenneth works for 42 hours next week, how much will he earn. A.255.00. B.12.00.
iren2701 [21]

Answer:

Kenneth will earn about $ 504 the next week

Step-by-step explanation:

The first thing we will have to figure out is how much Kenneth earns per hour. Then we can get how much he will earn when he wors for 42 hours.

to get Kenneth's wage per hour, we will divide the sum he is paid in the first week by the number of hours he worked that week.

This is 450/ 37.5 = 12 dollars per hour.

Kenneth earns $12 per hour.

If Kenneth works for 42 hours, he will earn 42 X 12 = $ 504 the next week
