Dont quote me on this but i think it is 10 because 86 × 2 is 172 and 297 ÷ 172 is 10 I think
2.15
1hr is 60 min so
60÷15=4
45miles×2hrs=90
45÷4=11.25
90+11.25=101.25 miles
101.25 miles÷ 25 miles per gallon= 4.05 gallons
4.05 gallons× $2.75 per gallon= $11.1375
$11.1375= $11.14

Answer:
x = 0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x+7)=−4x+14
(2)(x)+(2)(7)=−4x+14(Distribute)
2x+14=−4x+14
Step 2: Add 4x to both sides.
2x+14+4x=−4x+14+4x
6x+14=14
Step 3: Subtract 14 from both sides.
6x+14−14=14−14
6x=0
Step 4: Divide both sides by 6.
6x 0
6 =
6
x=0
