Answer:
15
Step-by-step explanation:
If A||B then the sum of given angles must be equal to 180°
2x + 5 + 5x - 80 = 180 add like terms
7x - 75 = 180 subtract 75 from both sides
7x = 105 divide both sides by 7
x = 15
I think its b or c but my best guess would be b
Answer:
rental fee = $6
average cost for 6 hours = $2.50/hour.
Step-by-step explanation:
x + 1.50*6 = 15 where x = the initial rental fee

x = $6
The rental fee is $6.
For 6 hours, the cost per hour works out to 15/6 = $2.50
Answer is A.
