Question

Simplify 15r+6(60-r) what are the units associated with the entire expression

Answer 1

so far, there is no units we can see becaus we have no context what this is trying to find


so
use the distributive property which goes like this: a(b+c)=ab+ac
so
first distribute

6(60-r)=6(60)+6(-r)=360-6r

now we have
15r+360-6r=
15r-6r+360=
9r+360
there are no units associated with the expression
