At one gas station, gas costs $2.75 per gallon. Write an equation that relates the total cost, C , to the number of gallons of gas purchased, g.

Answers

Answer:

C = 2.75g

Step-by-step explanation:

The total cost of the gas purchased is the product of the price per gallon and the number of gallons.

Hope this helps. :)

Final answer:

The equation that relates the total cost (C) to the number of gallons of gas (g) is C = 2.75g. This equation indicates that to find the total cost, you multiply the number of gallons by $2.75.

Explanation:

The question is asking for an equation that relates the total cost (C) to the number of gallons of gas purchased (g). Since the cost of gas is $2.75 per gallon, you multiply the number of gallons by $2.75 to find the total cost. Therefore, the equation that represents this relationship is C = 2.75g.

This equation states that the total cost (C) is equal to the cost per gallon ($2.75) multiplied by the number of gallons of gas (g). For instance, if you buy 10 gallons of gas, you would plug in 10 for g in the equation like this: C = 2.75 * 10, which will give you $27.50.

an athlete takes 10 rounds of a rectangular path, 70m long and 40m in wide. find the total distance covered by him.

Answers

Answer:

2,200 meters.

Step-by-step explanation:

Given that an athlete takes 10 rounds of a rectangular path, 70 meters long and 40 meters wide, in order to find the total distance covered by him the following calculation must be performed:

((40 + 70) x 2) x 10 = X

(110 x 2) x 10 = X

220 x 10 = X

2,200 = X

Thus, the total distance covered by the athlete was 2,200 meters.

Will give BRAINEST Solve the system of equations below by graphing both equations with a pencil and paper. What is the solution?

Answers

y = x + 1
y = 1/2x + 3

x + 1 = 1/2x + 3
x - 1/2x = 3 - 1
1/2x = 2
x = 2 / (1/2)
x = 2 * 2/1
x = 4

y = x + 1
y = 4 + 1
y = 5

so ur solution is : (4,5)
