Can someone plz help me with this?

10.

5x+23=8x-19

23+19=8x-5x

3x=42

x=42/3

x=14

11.

14x-13=8x+5

14x-8x=13+5

6x=18

x=18/6

x=3

.12.

4x+7=10x-41

10x-4x=41+7

6x=48

x=48/6

x=8

so

h=10×8-41=39

b=17

p=SV

By using Pythagoras law

p²+b²=h²

SV²=39²-17²

SV²=1232

SV=√1232

SV=35.09=35

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.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
