Answer:
y = -20
Step-by-step explanation:
Given that y varies directly with x it means changing x will also cause change in y
Mathematically it can be written as:
y∝x
Removing the proportionality symbol
y = kx
Given y=25 when x=5 Putting the values

Now

We have to find the value of y when x = -4
Putting x=-4

Hence,,
y = -20
1 hour = 60 minutes
60 minutes / 10 minutes = 6
So 6 times in one hour 3 buses depart.
6 x 3 = 18 total buses in an hour.

C. 6/5 * 4
6/5 = 1.20 where .20 represents the 20% increase in serving.
1.20 * 4 = 4.8 is the total cups of flour needed to increase serving by 20%
4 is the 100% ; the desired increase is 20%; therefore: 100% + 20% = 120% based on 4 cups. So, 120% ÷ 100% = 1.2 * 4 = 4.80 cups
