Answer:
150%
Step-by-step explanation:
What cards?
I don’t get it
48 students in group 2
43 students in group 1
So in total there are 91 students
7 students play the trump
And 20 play the trombone
Therefore it is known that 27 students play those two instruments in total
Because of this, Subtract 27 from 91 to get the num of students who doesn't play those instruments.
X=34
First add like terms in the equation so that you get the equation 3x-2=100. Next add 2 on both sides so that you then get 3x=102. Lastly divide by 3 on both sides to isolate x. You would then get x=34.
