Answer:

5 buses and 3 vans were taken.

Step-by-step explanation:

x+y=8

13x+5y=80

----------------

x=8-y

13(8-y)+5y=80

104-13y+5y=80

104-8y=80

8y=104-80

8y=24

y=24/8

y=3

x+3=8

x=8-3=5

x=5, y=3. (5, 3)

5 buses and 3 vans were taken.

A line passes through the points (6, 2) and (1, -1). Which is the equation of a line?
Illusion [34]

Answer:

3/5

Step-by-step explanation:

(6, 2) and (1, -1)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-1 - 2) / (1 - 6)

Simplify the parentheses.

= (-3) / (-5)

Simplify the fraction.

= -3/-5

= 3/5

This is your slope.

Hope this helps!
