Eddie compared prices of two auto-rental agencies for the use of a mid-size auto for one week. Right Price Auto charged a flat fee of $386 plus $0.20 per mile driven. EconoCar charged a flat fee of $344 plus $0.35 per mile driven. Which equation is written correctly, for the company he used to determine the distance in miles, m, that would make the total charges of both auto-rental agencies equal. Group of answer choices
Answer:
A. 386 + .20m = 344 + .35m
280 miles
Step-by-step explanation:
A. 386 + .20m = 344 + .35m
B. 344 + .20m = 386 + .35m
C. 344 + 20m = 386 + 35m
D. 386 + 20m = 344 + 35m
Right Price Auto charged a flat fee of $386 plus $0.20 per mile driven.
Right price auto = fixed charge + variable charge
= 386 + .20m
Where m = number of miles
EconoCar charged a flat fee of $344 plus $0.35 per mile driven.
EconoCar = fixed charge + variable charge
= 344 + .35m
Where m = number of miles
Equate the total charges of both auto-rental agencies
Right price auto = EconoCar
386 + .20m = 344 + .35m
Collect like terms
386 - 344 = .35m - .20m
42 = .15m
Divide both sides by .15
m = 42 / .15
= 280
m = 280 miles

Community Gym charges a $60 membership fee and a $55 monthly fee. Workout Gym charges a $200 membership fee and a $45 monthly fee. After how many months will the total amount of money paid to both gyms be the same? What will the amount be?
Answer:
4 Months, and the Total amount is 280
Step-by-step explanation:
60 + 55m = ?
200 + 45m = ?
60 + 55 = 115 + 55 = 170 + 55 = 225 + 55 = 280
200 + 45 = 245 + 45 = 290 + 45 = 235 + 45 = 280

solve for r. ( geometry )
Answer:
r i r
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, distribute. 12r + 16 = -16r - 40
Then get r on one side by adding 16r to both sides then subtracting 16 from both sides. 28r = -56
Finally, divide by 28 on both sides to get r by itself.
r = -2

Answer:
Tyler is correct. The temperature dropped at a rate of about 4° per hour between 4 and 6, while the temperature dropped at about 2.25° per hour between 6 and 10.
Edit: Explanation
The question is asking about which window of time had a faster decline in temperature, not a larger total change in temperature.
In a 2 hour timeframe, the temperature dropped 8°. (4-6 PM)
In a separate 4 hour timeframe, the temperature dropped 9°. (6-10 PM)
To find which window had a faster change in temp, I took the total temperature drop for each timeframe, then divided it by the number of hours each drop took.
8° / 2 = 4° per hour for 4-6 PM
9° / 4 = 2.25° per hour from 6-10 PM
Since the speed at which the temperature dropped per hour was greater from 4-6 PM than 6-10 PM, Tyler was correct.
Answer:
i agree with Mai because she/he (im not really sure) said that the temperature changed quicker in the time between 6 and 10 pm. the temperature change was 9 in those 4 hours.
Step-by-step explanation:
well there's a 4 hour difference between all 3 of the times
4 pm - 6pm
25 - 17 = 8
8 degree difference
6 pm - 10 pm
17 - 8 = 9
9 degree difference
the temperature changed quicker during 6 pm to 10 pm

Step-by-step explanation:
What is the equation of this graph?
A. y = 2x + 7
B. y = -2x + 7
C. y = -2/7x + 7
D. y = -7/2x + 7
E. y = -7/2x+ 2
Answer:
The equation would be Y= -7/2x + 7
Step-by-step explanation:
With the points given (0,7) and (2,0) we find our slope which is: -7/2. We know that our change in the y values is -7 and the change in our x values is +2. Y IS ALWAYS OVER X SO WE GET -7/2.
To find our y intercept you just look at the graph of where there's a point on the y line. For example (0,7) the 7 would be our y intercept.
So we get Y= -7/2x +7
The slope is ALWAYS put next to the variable x.
Hope this helps! :)
(Side Note: You look at the graph from left to right, so our first point would be (0,7)!)
Answer:
D. y= -7/2x +7
Step-by-step explanation:
From the graph we see that (0,7) is a point in which our line intersects on the y axis meaning that it will be our y intercept. Thus eliminating option E.
Next, we know that this graph is moving towards the left side of the graph meaning that the values will turn negative and thus meaning that the graph is decreasing, so our slope will be negative.
We know that slope is Rise/run. In thsi case, the graph doesn't have an even run of 2x or -2x because it doesn't intersect directly at those points. This eliminates A and B.
We are now left with Options C and D. Said before, 2 is our run in this graph because when observing the graph, we see that the point (2,0) is lowered by 7 and moved to the right 2. Meaning that 7 is our rise in this case and 2 would be our Run. But because it is negative pur slope is -7/2x.
Which eliminates C. Thus leaving option D as our answer
