Answer:

168 miles

Step-by-step explanation:

If he uses 5 gallons to drive 140 miles, that means that he can drive 24 miles for every gallon (140/5=24)

7 times 24 is 168 so he can drive 168 miles on 7 gallons of gas

Answer:

So the answer is A

Step-by-step explanation:

A)

f(x)=815.03(1.38)^{x}

f(1) = 1124.74

f(2)= 1552.143

f(3) = 2141.9575

f(4)= 2955.901

f(5)= 4079.1439

So the answer is A

B)

f(x)=1.38x^{2} -2.64x+815.03

f(1) = 813.77

wrong!

C)

f(x)= 1.38x+815.03

f(1) = 816.14

D)

f(x)=815.03\sqrt{x} -1.38

f(1)= 813.65

wrong!

Alexandria High School scored 37 points in a football game. Six points are awarded for each touchdown. After each
Dima020 [189]

Answer:

Five touchdowns were made in the game

Step-by-step explanation:

Here, we want to know the number of touchdowns made during the game.

We proceed as follows;

Let the number of touch downs be x

So the total points earned through touchdowns is 6 * x = 6x

The number of scores is 10 times

Let the number of extra kick be y which means that the number of conversions will be (y-1)

So the total number of score times will be ;

x + y + y-1 = 10

x + 2y = 11 •••••••••(i)

Now let’s work with points

Touch down points = 6 * x = 6x

Points from extra kick = 1 * y = y

Points from 2-point conversions = 2(y-1) = 2y - 2

So;

6x + y + 2y -2 = 37

6x + 3y = 37 + 2

6x + 3y = 39

divide through by 3

2x + y = 13 •••••••(ii)

So now solve simultaneously

From ii, y = 13 - 2x

Put this into i

x + 2(13-2x) = 11

x + 26 - 4x = 11

x -4x = 11-26

-3x = -15

x = -15/-3

x = 5

There are five touchdowns in the game
