Answer:
31/42
Step-by-step explanation:
there are 42 students in 8th grade
31 dont play keyboard so 31/42 = 73.8% chance
The answer is x=-20.
6+ -28 -x =-2
You first add 28 to each side=6+-x=26 then you minus 6 from each side=-x=20.
Then you divide 20 by -x resulting in x=-20
1/4=2/8 and 3/4=6/8... common denominator
2/8+5/8+1/8+2/8+2/8+2/8+6/8+6/8=26/8=13/4=3 1/4
77 - (-145) = 77 + 145 = 222
