Some people advise that in very cold weather, you should keep the gas tank in your car more than half full. lou's car had 6.2 gallons in the 14-gallon tank on the coldest day of the year. lou filled the tank with gas that cost $3.70 per gallon. how much did lou spend on gas?

$28.86

Step-by-step explanation:

14-6.2

=7.8

3.70 * 7.8

=28.86

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
