To solve for R you use PEMDAS
Answer:
79.8
Step-by-step explanation:
7.98*10=
79.8
to check
(1/10)*79.8=
7.98
Substituting y=6x+2 into equation 3y - 18x =12 looks like:
3(6x + 2) - 18x = 12
18x + 6 - 18x = 12 distributive property left side
6 = 12 simplifying the left side
We now see a contradiction: 6 does not equal 12 What this tells us is that there is no solutions to this equation. So choice 'C' ...
Here’s the correct answer and the way i got to it. Hope this helps :)
