Evelyn bought 8.4 gallons of gas for $23.94. which equation can be used to determine the price of each gallon of gas?

Step-by-step explanation:

Given :Evelyn bought 8.4 gallons of gas for $23.94.

To Find:Which equation can be used to determine the price of each gallon of gas?

Solution:

Let the cost of 1 gallon of gas be x

Cost of 8.4 gallons of gas = 8.4 x

Since we are given that cost of 8.4 gallons is $23.94.

So, A.T.Q

Or

Hence the equation can be used to determine the price of each gallon of gas is

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
