On his way to the library , Jeff runs two blocks and then walks three more blocks.Sketch a graph to show the distance Jeff travels compared to time.

Answers

Answer:

Since I can't take a picture, I am going to explain how to draw it.

Step-by-step explanation:

When sketching the graph you must note if jeff is going up the y-axis and along the x-axis. In this case, run means he goes up every minute. So when jeff runs he is going up and 2 minutes have gone by. And when he walks he is going up 3 more but slower so it would double the time. Time would be on the x-axis and blocks would be labeled on the y-axis.

Hope this helps. : )

Rapid Rental Car charges a $40 rental fee, $25 for gas, and $0.65 per mile driven. For the same car, Capital
Cars charges $55 for rental and gas and $0.75 per mile.
Part 1 out of 2
For how many miles is the rental cost at both companies the same?
The rental costs at both companies are the same at
miles.

Answers

Equation

40 + 15 + 0.25x = 45 + 0.35y

Solution

55 + 0.25x = 45 + 0.35y The only way you can do this is to assume that x and y are equal

subtract 45 from both sides

55 - 45 + 0.25x = 0.35x

10 + 0.25x = 0.35x Subtract 0.25x from both sides.

10 = 0.35x - 0.25x

10 = 0.1x Divide by 0.1

10/0.1 = x

x = 100 So if each car goes 100 miles, it should turn out to be the same no matter which company gets the rental.

Let's see if that is true.

Cost for the first company = 40 + 15 + 0.25x = 55 + 25 = 80 dollars.

Cost for the second company = 45 + 0.35x = 45 + 35 = 80 dollars.

Conclusion

Both rentals charge the same total amount when each car is driven 100 miles.

The charge is 80 dollars.

Fay has $__
Henry has $__

2. The sum of three consecutive numbers is 723. Find the numbers.

The answer that is worth the Brainliest has all the answers to my questions, and is correct.

Answers

Answer:

1. J=20, f= 28, H=42

2. 240 + 241 + 242 = 723

Step-by-step explanation:

J= 30- 12= 18+2= 20

F= 30-2=28

H=30+12=42

240 + 241 + 242 = 723

1. Jane has $40 to begin with
Fay has $32 to begin with
Henry has $18 to begin with

They all end with the same amount which must be 30.

40-12=28.- Jane 18+12=30- Henry
32-2=30-Fay. 28+2=30

2. 240+241+242= 723

The slop of the line is 1

Step-by-step explanation:

To find slop of the line you look at rise over run, or the distance from one point to another up then across. In this graph, from the point (0,-3) to (1,-2) you go up one point and across one point. 1/1 = 1 so the slope is 1.
