Answer:

The constant of variation is 1.6.

Step-by-step explanation:

y = kx and x = 5 when y = 8 and k = the constant of variation.

8 = k*5

k = 8.5 = 1.6.

Answer:

8/5

Step-by-step explanation:

Plug in the point given into

y=kx.

The number you get for y will be your constant of variation, also know as constant of proportionality.

(x,y)=(5,8) implies 8=k(5)

So in solving that equation we just need to divide both sides by 5 giving us:

8/5=k.

Answer:

Mia scored 6 baskets Last Saturday.

Step-by-step explanation:

Let:

Mia made score of baskets on Last Saturday = x

Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)

Total score of baskets = 24

We need to find How many baskets did Mia score last Saturday?

We can write:

<em>Total Score = Score on Last Saturday + Score yester</em>day

$24=x+3x$

Solving this equation we can find value of x:

$24=x+3x\\24=4x\\=>4x=24\\x=\frac{24}{4}\\x=6$

So, we get value of x = 6

Mia made score of baskets on Last Saturday = x = 6

Mia scored 6 baskets Last Saturday.
