Step-by-step explanation:
they are definitely rational numbers
I assume first equation is x-y=1. Solve for x in the first one in terms of y so you get x=y-1 so then you plug it in for x to get y-1+2y=8 then solve for y to get y=3 and then plug it into first equation to get x-3=1 and solve for x
Answer
x=4
y=3
Answer:
b pick 3 marbles form a bag of 10 different colored marbles
Step-by-step explanation:
1 cup = 8 fl oz.
So then we can set up a ratio of
So we get:
We cross multiply and we try to solve for x, so:
And the fl. oz. cancel out, and we are left with:
<u>So 22 fl. oz. equals to 2 3/4 cups.</u>
