PLS GIVE ME BRAINILIEST IF IT'S CORRECT!
Use the distributive property to multiply the two sets of parentheses. You should have learned this in Algebra 1.
9 is 25% of 36. That is the correct answer.
For this problem, we are going to have to use our order of operations, which is: Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction (often abbreviated PEMDAS).
First, let's see if there are any parentheses. There is one set of parentheses which we will have to remove. To do this, we will simply multiply the -4 by the 6, given us a value of -24 to take the place of the -4(6). Now our problem is:

Next, we will check for exponents. There are exponents, so we will need to take care of those.
is equal to 144, and
is equal to 121. We can now substitute these values into the original expression to get:

Now, we will check for any multiplication or division. Besides the entire expression (which is a fraction), there is none, so we will move on to the next step: Addition and Subtraction. You can see there is addition and subtraction in the numerator.
is equal to 120, and
is equal to 121. Our problem is now:

Our answer is 1.
Answer:
80 members
Step-by-step explanation:
Let the band members be= b and the chorale members= c
Then, according to question, b=c+30 and 
⇒
⇒
⇒
⇒
Now, substituting the value of b=c+30, we get
⇒
⇒
⇒
⇒
Therefore, 

Therefore, there are 80 members in the band.
