Kevin watches a concert at the theatre. The concert ends at 8:40 pm.
It takes Kevin 22 minutes to get from his seat in the theatre to the train station.
Trains to Kevin's home leave the train station at the following times:
19:15
20:15
20:35
21:15
21:35
22:15
22:35

a)
Write down the time of the earliest train that Kevin can catch.

b)
How long will Kevin have to wait at the train station for, if he catches the
earliest possible train?

After arriving at the train station, It would be 9:02 PM

Earliest Train: 21:15 (Or 9:15 PM)

He was to wait 13 minutes before he can ride the earliest train.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
