andrey2020 [161]

Total Distance = 4km

Each person takes 4/5km

Calculate the number of times the tent has to change hands:

$4 \div \dfrac{4}{5} = \dfrac{4}{1} \times \dfrac{5}{4} = \dfrac{5}{1} = 5$

$\boxed {\boxed { \text {Answer: The tent will have to change hands 5 times.} } \\ \\ }$

Suppose y varies directly with x, and y = 12 when x = 2. What direct variation

neonofarm [45]

Answer:

$y=24$

Step-by-step explanation:

Given:

$y=kx$

Substitute:

$\left \{ {{y=12} \atop {x=2}} \right.$ into $y=kx$

$12=k\times2$

Swap the sides:

$k\times2=12$

Divide both sides of the equation by the coefficient of variable:

$k=\frac{12}{2}$

Cross out the common factor:

$k=6$

Find the equation of the function:

$y=6x$

Substitute:

$y=6\times4$

Calculate the product or quotient:

$y=24$

What is the length of AC?

Blizzard [7]

Answer:

10 + 20 = 30

Step-by-step explanation:

If you subtract 5 from 25 you get 20 which is the length distance from b to c. Let's do the same to 15, 15 - 5 = 10. So now let's add our given lengths: 10 + 20 = 30.
