Answer:
9/11
Step-by-step explanation:
Well we know there are 55 students in total and only 45 of them can either play a string or brass instrument.
So 45/55 is 9/11
Thus probably is 9/11 of a randomly selected student who plays either a string or brass.
Answer:
x = 34
Step-by-step explanation:
The angles x + 12, 100, and x add up to a straight angle, so the sum of their measures is 180°.
(x + 12) + (100) + (x) = 180
x + 12 + 100 + x = 180
2x + 112 = 180
2x = 68
x = 34
