Jack has 20 more stamps than dylan has. together they have 46 stamps. find the number of stamps each has

The number of Jack's stamps is 33 and Dylan's stamps is 13

Step-by-step explanation:

Let

x > the number of Jack's stamps

y > the number of Dylan's stamps

we know that

x+y=46 > equation A

x=y+20 > equation B

Solve by substitution

substitute equation B in equation A and solve for y

(y+20)+y=46

2y=46-20

2y=26

y=13 stamps

Fond the value of x

x=y+20 > x=13+20=33 stamps

therefore

The number of Jack's stamps is 33 and Dylan's stamps is 13

Jack has 33 stamps and Dylan has 13 stamps .

Step-by-step explanation:

Let x be the number of stamps Jack has and the number of stamps Dylan y.

Adding equation (1) and (2), we get

From (1), we have

Hence, Jack has 33 stamps and Dylan has 13 stamps .

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
