Answer:
Let's denote students in D = in the drama club , S = in a sports team
P(D) = 85/330
P(S) = 200/330
P(D and S) = 60/300
P(D or S) = P(D) + P(S) - P(D and S) = 85/330 + 200/330 - 60/330 = 15/22
P(neither D nor S) = 1- 15/22 = 7/22

Make the variable in bracket the subject
From the given expression, none of the variables (m and x) are in brackets.
So, I will solve for m and then solve for x
Solving for m:
Subtract 2x from both sides
Divide both sides by x
Solving for x:
Factorize
Divide both sides by m + 2
Step-by-step explanation:
Ashley is the utilities manager at a paper mill. She's watching over one of her holding tanks. It takes 4/5 of an hour to fill 1/2 the tank
First we convert 4/5 of an hour in to
minutes
4/5 6048 minutes
In 48 minutes ----> 1/2 tank filled
In 60 minutes ----> 60 * 1/2 divide by 48
30 divide by 48=\frac{30}{48}
48
30
All 15%
Simplify the fraction by dividing top and
bottom by 6
30/48 = 5/8
