Answer:
14 gallons of a gas more will she need to travel 240 miles.
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
Let x represents the more gallons will she need to travel 240 miles.
As per the statement:
12 gallons of gas to travel 144 miles. Six gallons in the tank.
Then;
By definition of proportion:
![\frac{12}{144} = \frac{x+6}{240}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B144%7D%20%3D%20%5Cfrac%7Bx%2B6%7D%7B240%7D)
Multiply 240 to both sides of an equation we have;
![\frac{12}{144} \times 240 = x+6](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B144%7D%20%5Ctimes%20240%20%3D%20x%2B6)
Simplify:
![20 = x+6](https://tex.z-dn.net/?f=20%20%3D%20x%2B6)
Subtract 6 from both sides we get;
![14 = x](https://tex.z-dn.net/?f=14%20%3D%20x)
Therefore, 14 gallons of a gas more will she need to travel 240 miles.
Answer and Step-by-step explanation:
Simply add the expression together, then subtract the sum of the other expression
is the answer.

Answer:
Y=45x
Step-by-step explanation:
Y = f(x)
If you plot a chart, you can find that relation is just a linear relation. So y = mx + c
By putting any one case into the equation, you can find c = 0 and m = 45
Retest the equation for other cases to ensure u are correct

Answer:
u know area of rectangle is length × breadth
therefore, area = (3x+4)×(7x-2)
= 21x²-6x+28x-8
= 21x²+22x-8
