The Freeman family:
13 c/kWh (400 kWh) + 2 c/kWh (400 kWh) + 14.5 c/kWh) 450 kWh
= 6464.5 c
6464.5 c x 30 = 193935
The Baum family:
8.5 (400) + 12 (400) + 14.5 (450)
= 14725 c
<span>The Freeman family pays $260.83 more than the Baum family.

Angles ∠ACD and ∠CAB are congruent because they are alternate angles. Then the area of the triangle AOB will be 22.53 square cm.
<h3>What is the
area of the right-angle triangle?</h3>
The area of the right-angle triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the right triangle.
We know that angles ∠ACD and ∠CAB are congruent because they are alternate angles.
α₁ = 40°
AO = OC = 7.8 cm
Then the area of the triangle will be
Area = 1/2 x 7.8 x 7.8 x tan40°
Area = 22.53 square cm

Step-by-step explanation:
Answer:
4.
3.
2.
1.
Step-by-step explanation:
4. 7x - 2 = 9x + 10
- 9x + 2 - 9x + 2
_____________
3. 4x + 8 = 3(x - 1) + 12
4x + 8 = 3x - 3 + 12
4x + 8 = 3x + 9
- 4x - 9 - 4x - 9
____________
2. 3x + 7 - 2x = 4x + 10
x + 7 = 4x + 10
- 4x - 7 - 4x - 7
____________
1. −2x + 8 = 2x + 4
- 2x - 8 - 2x - 8
