3/6 =1/2
Answer:
always
Step-by-step explanation:
becouse it is has a angle
1/4 time 1/4 equals a half...or you can think about it as 25 plus 25 equals 50, (1/2 of a dollar)
Combine like terms:
-r-10r
We can always add variables as long as they are the same. So we can not add 10x+20y. That's impossible.
We can't add 3r^2+10r. That's also impossible.
However, we have the same variable, r. So we can add -r-10r. And the answer is:
-11r
Hope this helps! :)
