Answer:
(Infinitely), (No solution), (One solution), (One solution)
Step-by-step explanation:
1. 5x + 9 = 9 + 5x (Infinitely)
2. -4x + 8 = -4x - 8 [minus -4x from both equation, we get 8 = -8, which is impossible] (No solution)
3. x - 3 = 3 - x [2x = 6, x = 3] (One solution)
4. 3x + 7 = 7x + 3 [4x = 4, x = 1] (One solution)

Answer:
Step-by-step explanation:
Let x represent the distance that the truck was driven.
Buck rented a truck for $39.95 plus $0.32 per mile. This means that the total cost of driving x miles with the truck would be
39.95 + 0.32x
Before returning the truck, he Filled the tank with gasoline, which cost $9.85. This means that the total amount that he spent is
39.95 + 0.32x + 9.85
If the total cost was $70.23, it means that
39.95 + 0.32x + 9.85 = 70.23
49.8 + 0.32x = 70.23
0.32x = 70.23 - 49.8 = 20.43
x = 20.43/0.32 = 63.8
Approximately 64 miles

Determine which has a better value
First, we calculate the unit rate of both.
For the family size:
For the mega size:
<em>By comparing the unit rates, the mega size has a better value because it costs cheaper per unit rate</em>
