Answer:
3. B.
1. 3551.
Step-by-step explanation:
3. For two equations to have infinite solutions, the equations must be the same.
y = -5x + 6
5x + y - 6 = 0
Multiply the whole thing by 2.
10x + 2y - 12 = 0
B.
1. Michelle rides roller coasters 3 times and plays the super swing 5 times, which means that A = 3 and B = 5.
Marty rides the roller coasters 5 times and plays the super swing 1 time. That means C = 5 and D = 1.
So, your answer will be 3551.
Hope this helps!

Answer:
The inequality that represents this statement is 99 + 0.2*miles <= 200 and Melissa has to drive 505 miles or less on her vacation.
Step-by-step explanation:
In order to solve this problem we can first create an equation that represents the total paid in function of the miles driven. We have:
total paid = 99 + 0.2*miles
Since Melissa can oly pay $200 for the rent, then the total paid by her must be less or equal to this value so we have:
99 + 0.2*miles <= 200
0.2*miles <= 200 - 99
0.2*miles <= 101
miles <= 101/0.2
miles <= 505 miles
The inequality that represents this statement is 99 + 0.2*miles <= 200 and Melissa has to drive 505 miles or less on her vacation.
