We will use the ratio and proportion method ( an equation formed with two ratios that are equal) to solve the question “if <span>it takes 18 gallons of gas to go 400 miles, how many gallons would it take to go 300 miles?” </span>
<span>Let x= the number of gallons for the gas to go 300 miles</span>
18:400=X:300
400x=300*18
400x=5400
X=5400/400
<span>X=13.5 so the answer is B.</span>
Answer:
7x-1
Step-by-step explanation:
you have to combine like terms
48 feet
Divide 858 by 18 to get 47.6 > simplify > 48 feet
2x^2(x+2) +6(x+2) = (2x^2 +6)(x+2) = 2(x^2 +3)(x+2)
so this mean that the 4th choice will be right sure
