Answer:
C. It is the total cost of the membership fee and the tire pressure check for 12 months.
Step-by-step explanation:
The constant represents the sum of costs that are <em>not</em> "per car." Those are only "membership fee" ($50) and "tire pressure check" ($15/mo × 12 mo = $180).
Answer:
5 1/3 hours.
Step-by-step explanation:
Ashley prepares 1 bag in 2/3 minutes.
One friend takes 2/3 + 3/4 * 2/3 = 7/6 minutes to make 1 bag.
4 of her friends can make 1 bag in 7/6 * 1/4 = 7/24 minutes.
If it takes x minutes for Ashley and 4 friends to make one bag then we have:
1 / 2/3 + 1 / 7/24 = 1 / x
3/2 + 24/7 = 1/x
Multiply through by 14x:
21x + 48x = 14
x = 14/69 minutes.
So the time to make 1575 bags = 1575 * 14/69
= 320 minutes.

Answer:
see explanation
Step-by-step explanation:
A monomial is an expression with one term
A binomial is an expression with 2 terms
A trinomial is an expression with 3 terms
Thus
- 2x² - x + 3.5 ← has 3 terms, hence trinomial
10xyz³ ← has 1 term, hence monomial
- x²y² + 2y ← has 2 terms, hence binomial
8x² + 0.25 ← has 2 terms, hence binomial
x³
+ 2x²y - 3x ← has 3 terms, hence trinomial
