Max car holds 18 gallons of gasoline driving on the highway the car uses approximately 2 gallons per hour. let H represent the number of hours max has been riding on the highway. write an expression that shows how many gallons of gasoline Max has left after driving H hours. then find the number after max drives 3.5 hours on the highway.

Answers

y= 18 gallons-2(h)
y is what you're trying to find out and since there are 18 gallons in the tank after every hour you would have 2 less gallons. So, you can multiply how many hours he's been driving by the 2 gallons and subtract it from 18

Answers

Answer:

a) total cost of downloading B is £11.90

b) total cost of downloading B is £12.04

see if that looks right lol

Step-by-step explanation:

a) £9.35 = 935p

935÷11=85p (cost per track)

85 x 14 = 1190p

1190p = £11.90

b) 85 x 6 = 510p

7 x 6 = 42p

510 - 42 = 468p

85 x 8 = 680p

7 x 8 = 56

680 + 56 = 736p

468 + 736 = 1204p

1204p = £12.04

What are the first five terms of the sequence represented by the explicit equation g(n) = 34 - 5n ?

Answers

Answer:

Step-by-step explanation:

Remark

My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)

What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.

zero

n = 0

g(0) = 34 - 5*0

g(0) = 34

One

n = 1

g(1) = 34 - 5*1

g(1) = 34 - 5

g(1) = 29

Two

g(2) = 34 - 5*2

g(2) = 34 - 10

g(2) = 24

Three

g(3) = 34 - 5*3

g(3) = 34 - 15

g(3) = 19

Four

g(4) = 34 - 5*4

g(4) = 34 - 20

g(4) = 19

What is the time of the latest train that she can catch to get to work on time? C) how long does the train take to travel from the westchester to east wick?

Answers

Answer:

a). 6:51

b). 6:30 am

c). 34 minutes

Step-by-step explanation:

a). Train leaves Westchester at 6:30.

    From the arrival - departure table in column (2),

    Arrival time of the train at middlewich = 6:51

b). Kate has to reach Southam before 9:00 am

    Therefore, time of the latest train that she can catch to get to work on time is 6:30 am

     By this train she can reach at 07:19 at Southam.

c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00

                                                                                         = 00:34

                                                                                         ≈ 34 minutes

A student wrote a list of six consecutive integers. If the sum of the first integer and sixth integer is 1, which integer is the least of the six integers?
A. -2
B. 1
C. 3
D. 5

Answers

Answer:

A

Step-by-step explanation:

The student wrote a list of six consecutive integers.

The sum of the first integer and the sixth is 1.

Let the first integer be represented by n.

Then the subsequent integer will be (n + 1).

Therefore, our sequence is:

n, n + 1, n + 2, n + 3, n + 4, and n + 5.

The sum of the first and sixth is 1. Therefore:

[tex](n)+(n+5)=1[/tex]

Solve for n. Combine like terms:

[tex]2n+5=1[/tex]

Thus:

[tex]2n=-4[/tex]

And:

[tex]n=-2[/tex]

Thus, our first term is -2.

Therefore, our sequence is:

-2, -1, 0, 1, 2, 3

The least of the six integers is -2.

Our answer is A.

A
