Answer:
c = 27
Step-by-step explanation:
If c divided by 9 equals to 3, then the other way around would be 3 times 9 equals to c, which is how you would get 27. If you look at PEMDAS, multiplication and division are together and work the other way around when used with each other, just like addition and subtraction.
I know this is kind of a lame answer with no fancy math words to back it but please, it's the best I could do.
Function I’m just guessing?
Answer:
30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
