If P is between L and A, PL = x + 4, PA = 2x − 1, and
LA = 5x − 3, then x = and LA = .

x=3 LA=12

Step-by-step explanation:

PL plus PA is equivalent to LA. So, (x+4)+(2x-1)=5x-3, which can be rewritten as 3x+3=5x-3. Now we can add 3 to both sides to get 3x+6=5x and subtract 3x from both sides to get 6=2x. Now we divide by 2 on both sides to get x, which is 3, and we can plug that into the equation for LA. So we get 5(3)-2=LA. LA equals 12.

Steps to solve (x+4)+(2x-1)=5x-3:

1: (x+4)+(2x-1)=5x-3

2: 3x+3=5x-3 Rewrite equation

3: 3x+6=5x Add 3 to both sides

4: 6=2x Subtract 3x from both sides

5: 3=x Divide by 2 on both sides

the answer for this question is 38

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.
