Answer:

x = 5

y = 4

Step-by-step explanation:

multiply the second equation by -1 and add the first equation to eliminate "x"

4x+6y=44\\-4x-2y=-28
_____________

       4y=16

y=16/4 =4

Replace "y" in the first equation:

4x+6(4)=44

4x+24=44

4x=44-24

x=20/4=5

Hope this helps

Answer:

x = 5, y = 4.

Step-by-step explanation:

4x + 6y = 44        (A)

4x + 2y = 28        (B)

Subtract equations: (A) - (B).

0 + 4y = 16

y = 16/4

y = 4.

Now plug y = 4 into equation A:

4x + 6(4) = 44

4x = 44 - 24

4x = 20

x = 5.

Now check if these roots are correct by plugging them into equation B:

4x + 2y = 28

4(5) + 2(4) = 28   - check OK.

Lucy earns ​$5.50 per hour at a local restaurant. She earns time and a half for each hour she works on a holiday. Lucy worked se
Mrrafil [7]
X will be used for the value of money she earned that week.

H represents the normal hours she worked.

D represents the number of days.

Y will represent the hours on the holiday.

Since she would be getting time and a half on the holiday, you would need to find how much time and a half pay would be first.

Time and a half = 5.50(1/2) + 5.50 = $8.25/hr for the day or holiday only.

X = 5.50(H)(D) + 8.25(Y)

Plug in your numbers

X = 5.50(7)(5) + 8.25(4)

X = 192.5 + 33

She made $225.5 that week.
