One of the cars are blue it van travel 31 1/2 miles on 1 1/4 gallons of gasoline .Another car is red it can travel 28 4/5 miles
yuradex [85]

Answer:

Step-by-step explanation:

One of the cars are blue. it can travel 31 1/2 miles on 1 1/4 gallons of gasoline. Converting 31 1/2 miles to decimal, it becomes 31.5 miles. Converting 1 1/4 gallons of gasoline to decimal, it becomes 1.25 gallons of gasoline.

Therefore, the miles per gallon for the blue car is

31.5/1.25 = 25.2 miles per gallon.

Another car is red it can travel 28 4/5 miles on 4/5 gallon of gasoline.

Converting 28 4/5 miles to decimal, it becomes 28.8 miles. Converting 4/5 gallons of gasoline to decimal, it becomes 0.8 gallons of gasoline.

Therefore, the miles per gallon for the red car is

28.8/0.8 = 36 miles per gallon.

What is BC will give brainliest
Alexxandr [17]

Because two angles are equal, sides AB and AC will have equal lengths, and so, we can set each expression equal to each-other.

4x + 4 = 6x - 14

Subtract 4x from both sides.

4 = 2x - 14

Add 14 to both sides.

18 = 2x

Divide both sides by 2.

x = 9.

Because we have a constant value of x, we can solve for BC.

BC = 2x + 7

2(9) + 7

18 + 7

25

<h3>The value of BC is 25.</h3>
