Answer:
$250
Step-by-step explanation:
The numbers in the table indicate a proportional relationship between earnings and hours worked. Among other things, that means you can find the earnings for 20 hours by using any table values that sum to 20 hours.
For example, 9 hours + 11 hours = 20 hours, so the earnings would be ...
$112.50 +137.50 = $250.00 . . . for 20 hours
You could also use 4×5 hours = 20 hours, so ...
4×$62.50 = $250 . . . for 20 hours
__
Or, you can figure ...
$37.50/(3 h) = $12.50/h
so the pay for 20 hours is ...
(20 h)×($12.50/h) = $250.00
Answer:
-2(57+8) = 14 + 6x
step 1 -2 x 57 and -2 x 8 =
step 2 -114-16 = 14 + 6x
+16 +16
step 3 -114 = 30 + 6x
-30 -30
step 4 -144 = 6x
-144/6 6/6
x = -24
-2(5x + 8) = 14 + 6x
step 1 -2 x 5x and -2 x 8 =
-10x - 16 = 14 + 6x
step 2 -6x -6x
-16x -16 = 14
step 3 +16 +16
-16x = 30
step 4 -16/-16 30/-16
x= -15/8
