You simply use this operation:
- total students are 305, we need to find how many of thm play instrumenst if 40% does.
40% can be rewrited as 0,4 in decimal.
than we simply utilise a basic percentage operation which allows us to find A PART of somethin=>
305×0,4= students who instruments.
-1/8(x + 35)= -7
Use distributive property(Multiply -1/8 by x and 35)
-1/8x - 35/8= -7
Add 35/8 to both sides.
-1/8x= -21/8
Divide -1/8 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: 1/21
