Answer:
Step-by-step explanation:
-81=-5(v+5)-2v Original equation
-81=-5v-25-2v Distributive property
-81=-7v-25 Subtract like terms
-56=-7v Simplify
8=v Simplify
The car goes 23.2 miles every gallon, so with 15 gallons (15 * 23.2 = 348) it can go 348 miles. With the extra .25 that the car has, it can go 0.25 * 23.2 = 5.8 miles. 348 miles plus the 5.8 miles gets you 353.8 miles on 15.25 gallons.
Here, you have to foil the equation.
Distribute 4x to all sides, then distribute the -3 to all sides. Next, combine like terms. If you do this, your answer will be
