1/6 divided by 3 is 1/18
1/6÷3/1 then do reciprocal so it is 1/6×1/3 equals 1/18
Answer:
Step-by-step explanation:
15,218 - 4,379
=10,839
set bottom equation to look like first one.
2x+4y=4
this equation is the same equation as the first just multiplied by 2. the answer is c. infinite solutions. you can plug in and solve:
solve bottom equation equal to y, you get y=-1/2x+1
plug into top equation
x+2(-1/2x+1)=2
x-x+2=2
2=2
because that is a true statement it is c. infinite solutions
