Answer:
Step-by-step explanation:
K = A + 17
K + A = 117
A + 17 + A = 117
2A + 17 = 117
2A = 117 - 17
2A = 100
A = 100/2
A = 50 <=== what Allen sold
K + A = 117
K + 50 = 117
K = 117 - 50
K = 67 <==== what Kay sold
Plug in the known variables.

Answer:
r represents the rate the electric company charges per kilowatt-hour.
Step-by-step explanation:
r represents the rate the electric company charges per kilowatt-hour.
Total charged to Zhao was 63.25 out of which 3.50 is administrative charge (fixed).
- Total charge consists of "administrative charge" + "charge per kilowatt hours*hours used
- The equation is given as 63.24 = 3.5 + 800r
<u>Matching the "word equation" with "mathematical equation", we see that 800 is the hours used and r is the charge per kilowatt hour.</u>
F(h(x)) means wherever you see x in the f(x) function you're gonna plug in the h(x) function:
f(h(x)) = (2x + 3) - 7
= 2x + 3 - 7
= 2x - 4
2o + 3a = $45
