Edward's school is 13/2 miles away from his home . he goes by car to school and back. the car consumed 4 gallons of gas taking him to and from school over 5 days. what distance did he travel per gallon of fuel?

16.25

Step-by-step explanation:

Well, the school is 13/2 miles away.

13/2 = 6.5

Since Edward goes by car there and back, he travels 13 miles a day.

6.5 x 2 = 13

He went for 5 days.

5 x 13 = 65

The car consumed 4 gallons of gas by driving those 65 miles.

65 / 4 = 16.25

Therefore, Edward's car gets 16.25 miles per gallon!

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

5x+10 is the correct one

hope this
