Answer:
number of students in a van=12
number of students in a bus=52
Step-by-step explanation:
let number of students in a van=x
number of students in a bus=y
1x+6y=324 ...(1)
9x+3y=264 ...(2)
multiply (2) by 2
18x+6y=528 ...(3)
(3)-(1) gives
17x=204
x=204/17=12
put in (1)
12+6y=324
6y=324-12=312
y=312/6=52
<span>You have to calculate two separate measures, one for each set.The mean-to-MAD ratio is the mean divided by the MAD, i. e. mean / MAD. For the set 1, mean = 10.7 and MAD = 2.4, then mean / MAD = 10.7 / 2.4 = 4.4583. For the set 2, mean = 13.7 and MAD is 2.5, so mean/ MAD = 13.7 / 2.5 = 5.480.</span>
Answer:
y = 80-16x
Step-by-step explanation:
She made a total of 80 cups and sells 16 cups per hour
So in x hours she would have sold 16 * x = 16x cups
So the number of cups remaining will be;
y = 80-16x
