Answer:
X = 5/12
Step-by-step explanation:
(-1/3) = X - (3/4)
(-4/12) = X - (9/12)
+(9/12) +(9/12)
5/12 = X
I'm pretty sure that 20 students would be the answer
22/7-2/3 divided by 2. first, you would do 2/3 divided by 2, which can be rewritten as 2/3 times 1/2, which is 2/6. 2/6 can be simplified as 1/3. next, you do 22/7-1/3, which is 59/21, or 2 17/21.
this is the way to solve it
The answer is 71 because it has to add up to 180
