Answer:
x = 15.33
Step-by-step explanation:
3y is equal to 2x + 13. The reason why is because they are corresponding angles, (right next to each other). From there, you would have to substitute y into 3y. The equation should look like: 3(23) = 2x + 13. All that is left is to solve for x.
Step-by-step explanation:
P = IV
2000 W = I (120 V)
I = 16.7 A
P = E/t
P = (2000 W × 8 hr) / (1 day)
P = 16,000 W·hr/day
P = 16000 W·hr/day × (365 day / yr)
P = 5,840,000 W·hr/yr
P = 5,840,000 W·hr/yr × (1 kW / 1000 W)
P = 5840 kW·hr/yr
C = 5840 kW·hr/yr × (0.25 $/kW/hr)
C = $1460/yr
