The truck can travel 48 miles with 6 gallons.
Because if you divide 56(miles) by 7(gallons), you will get 8. 8 is the miles per gallon. so if you multiply 8(miles per gallon) by 6(gallons) you will get 48 which is how far the truck can travel on 8 gallons of fuel.

Hope this helps

Answer:No; $\frac{7}{56}$ and $\frac{48}{6}$ are not proportional because 7x6 isn't equal to 48x6

A triangle has a height that is 2 inches more than three times the base and an area of 60 in. Find the base and the height of th

const2013 [10]

Answer:

Height = 20, Base = 6

Step-by-step explanation:

The area of a triangle is $\frac{bh}{2}$

where b is the base and h is the height

$H = 3B + 2\\\frac{B(3B + 2)}{2}=60\\\\3B^2 + 2B = 120\\3B^2+2B - 120=0\\$

We can factor by grouping

$3B^2 - 18B + 20B - 120 = 0\\3B(B - 6) + 20(B-6) = 0\\GCF the (B-6)\\(B-6)(3B+20)=0\\B = 6, B = \frac{-20}{3}$

Length can only be positive, so we know that the base is 6 in

The height must be 2 + 3(6) = 20

Height = 20, Base = 6
