C. x+6 is a factor
...............
30 degrees. A triangle is 180. The right angle is 90.
90=7x-10+3x
add ten to both sides and combine like terms
100=10x simplify
10=x now substitute
3x
3(10)=30
The answer is b ...........................
You first need to multiply 22 by 475 since it is asking us how much in 22 months. So 22 x 475= 10,450. Then the question is asking us how much money left to pay after the 22 months so you subtract 10,450 from 12,750. Which is 12,750-10,450=2300 dollars.
Hope I helped!
Equation: 12,750-(22x475)
Answer:2300
