Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
The unit rate of gas usage is 35 miles per gallon.
Step-by-step explanation:
"Unit rate" refers to the number of miles for 1 gallon.
<u>From the graph given</u>,
it can be determined that, the car goes 2 miles for 70 gallons and 3 miles for 105 gallons.
To find miles per gallon, <u>use rate formula</u>
Rate= <em>Given miles/ Given gallons</em>= 2/70
Unit Rate= <em>miles/ 1 gallon</em>= X/1
where "X" term refers to number of miles per gallon.
By Comparing the rates we get,
2/70 =X/1
<u>X=35 miles per gallon</u>
Similarly,
3/105 =X/1
<u>X=35 miles per gallon</u>
