3.5 would be halfway of 3 and 4.

Answer:3.5

Step-by-step explanation:

3.5 is half of 3 and 4

Answer:

After 7.8 hours (7 hours 48 min.) will the bus and car be 800 miles apart

70(h-2) expression represents the number of miles the car travels.

Step-by-step explanation:

If h represents the number of hours the bus travels.

In the question it is said that the bus leaves 2 hours before the car does

Therefore car travels (Time) = ( h-2 )

car's speed = 70 mph,

Distance = speed × time = 70(h-2)

70(h - 2) expression represents the number of miles the car travels.

If we want to find the number of hours will the bus and car be 800 miles apart we can solve it as :

50h + 70(h-2) = 800

50h + 70h - 140 = 800

120h = 800 + 140

120h = 940

h = 940 ÷ 120 = 7.833... = 7.8 hours (7 hours and 48 min.)

Ans. After the bus left the city, after 7.8 hours the car and the bus will be 800 miles apart.

Simplify the expressions by using the distributive property.

For second expression,

To begin this problem, we need to use the two points that we are given to find the slope of the line. Slope is defined as the change in y values divided by the change in x values, or rise/run, and is represented by the variable m.

m = (y1-y2)/(x1-x2) = (8-0)/(3-6) = 8/(-3) = -8/3

Now, we can use the slope and one of the points from our given values to create an equation of the line in point-slope form.

y = m(x-h) + k, where a point on the line is (h,k)

y = -8/3(x - 3) + 8

Now, we can distribute our slope and simplify through addition.

y = -8/3x + 8 + 8

y = -8/3x + 16

Therefore, your answer is y = -8/3x + 16.

Hope this helps!
