<h3>
Answer: n+15</h3>
=======================================================
Explanation:
- n = number of minutes
- cost of company X = 3n+30
- cost of company Y = 2n+15
To find out how much more company X charges, we subtract the two cost expressions
CompanyX - CompanyY = (3n+30)-(2n+15) = 3n+30-2n-15 = n+15 which is the final answer.
--------------
An example:
Let's say you talk on the phone for n = 20 minutes.
Company X would charge you 3n+30 = 3*20+30 = 90 cents
Company Y would charge you 2n+15 = 2*20+15 = 55 cents
The difference of which is 90-55 = 35 cents.
If you plugged n = 20 into the n+15 expression we got, then n+15 = 20+15 = 35 matches up with the previous 35 cents.
This example helps confirm the answer. I'll let you try out other examples.
C I think sorry I will try I will get other answers later
Answer:
3). 8x +36 from simplifying the equation
Answer:
0.833 miles
Step-by-step explanation:
Because you know the area, you can use the formula for area of a rectangle. Just plug in what you know and solve.

30/54 is the same as 5/9.

Multiply by its denominator.

Simplify

Divide by 30

5/6 is roughly 0.833
Answer:
20
Step-by-step explanation:
4 + 5 = 9
