Doug earns $10.50 per hour working at a restaurant. On Friday he spent 1 3/4 hours cleaning, 2 1/3 hours doing paperwork, and 1 5/12 hours serving customers. What were Doug's earnings?A$46.97B$47.25C$53.00D$57.75

$57.75

Step-by-step explanation:

The total hours spent working :

1 3/4 + 2 1/3 + 1 5/12

7/4 + 7/3 + 17/12

L.C.M = 12

(21 + 28 + 17) / 12

= 66 / 12

= 5 6/12

= 5 1/2

Hourly pay = $10. 50

Total earning :

Total hours * pay per hour

5.5 hours * $10.50

= $57.75

x = -6

Step-by-step explanation:

Step 1: Write out equation

5x + (-2) = 6x + 4

Step 2: Simplify

5x - 2 = 6x + 4

Step 3: Subtract 5x on both sides

-2 = x + 4

Step 4: Subtract 4 on both sides

-6 = x

Step 5: Rewrite

x = -6
