So first you add 8 and 2 to get 10. This means that Kevin is 10 years old now. If he is currently twice as old as his brother it means that you divide 10 by 2 to get 5. Kevin's brother is 5 years old.
Answer: 5 years old
Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 8, 22) and (x₂, y₂ ) = (3, 0)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 0), then
0 = - 6 + c ⇒ c = 0 + 6 = 6
y = - 2x + 6 ← equation of line
Answer:
Approximately 6 buses
Step-by-step explanation:
If you are wanting know how many vans they are going to need:
26 + 32 -This helps you know how many total kids there are
= 58
58 / 10 -This solves how many buses you'll need
= 5.8 - Round up, and say you need 6 buses.
