It should be B. right angle and C. complementary angles
Step 1: You can distribute it by multiplying 6 by 2x and -12, so you get 12x-72= 24
Step 2: Now you can solve it by adding 72 on both sides, so we get 12x= 96, then you can divide 12 on both sides, so we get x=8.
Answer:
<h2>
Bike A costs $270 and has an expected maintenance cost of $36 per year.</h2><h2 /><h3>
"Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years."</h3>
Step-by-step explanation:
270-36x
there are 5 years so x=5
270 + 36(5) = 270 + 180 = <u>450</u>
If it were 6 years than x = 6
270 + 36(6) = 270 + 216 = <u>486</u>
Bike B:
360 + 20x
For option b x = 5
360 + 20(5) = 360 + 100 = 460
for option b it would be 6 years than x = 6
360 + 20(6) = 360 + 120 = <u>480</u>
