Hi there!
You should always find the value inside the parenthesis first when simplifying an equation.
Tell me if you need help solving the equation!
Hope this helps!
When it says to use distributive property, it means that you are going to "distribute" a variable and/or number to others.
To solve this (n+t)r .... then you would multiply "r" to "n" and then to "t".
It would end up looking like this... nr+tr .
This is your final answer because nothing else can be done to it. :)
I hope I helped you understand.
A + b = 6
a - b = 4
We substract those equations, we get:
2b = 2 (dividing both sides with 2)
b = 1
a = b + 4 (look at second aquations)
= 1 + 4
= 5
Answer:
1. Rate
2. unit
3. not sure what this one is sadly
4. ratio
5. dividing
