Sally ⇒
4 hours = 1 room
1 hour = 1/4 of the room
Steve ⇒
9 hours = 1 room
1 hour = 1/9 of the room
Sally + Steve ⇒
1 hour = 1/4 + 1/9 = 9/36 + 4/36 = 13/36
Number of hours needed ⇒
1 ÷ 13/36 = 1 x 36/13 = 36/13 = 2 10/13 hours
Answer: They need 2 10/13 hours.
Answer:
The constant of variation is k = -2 ⇒ (B)
Step-by-step explanation:
The equation of the direct variation is y = k x, where
- k is the constant of variation
- The constant of variation k =
The given table has 4 points (-1, 2), (0, 0), (2, -4), (5, -10)
We can use one of the points <em>[except point (0, 0)]</em> to find the value of k
∵ (-1, 2) is a given point
∴ x = -1 and y = 2
∵ k =
→ Substitute the values of x and y in the relation above
∴ k =
∴ k = -2
The constant of variation is k = -2

Answer:
16 rides
Step-by-step explanation:
If he has $12 in total and each ride costs 75 cents, you can divide 12 by .75 to find how many rides he can go on.
12/0.75 = 16
