Label equation 1 and equation 2,
Then 4y can be cancelled down from both, so we would do equation 1 plus equation 2,
Once you did equation 1 plus equation 2 you should have :
6x=-8
So X= -4/3
Then we would sub x into equation 2,
So it would be, 4/3+4y= -2
Y=-5/6
So final answer is
X = -4/3 Y= -5/6
The point of the y-coordinate would drop down below the x-axis.
You have:
<span>Cost in dollars --> $2.89 </span>
<span>Total ounces --> 4.25 </span>
<span>But you want to know the per unit cost for *1* ounce. </span>
<span>You have the right method. You want cost ($) per ounce so put the price over the amount in ounces. </span>
<span>2.89 / 4.25 = x / 1 </span>
<span>If you notice, since the denominator is 1, this is simply: </span>
<span>x = 2.89 / 4.25 </span>
<span>So the unit cost is just $2.89 divided by the number of ounces (4.25). </span>
<span>Plug that into your calculator and you get: </span>
<span>0.68 </span>
<span>That's in dollars. So if you want it in cents, move the decimal point 2 places to the right. </span>
<span>Answer: </span>
<span>$0.68 per ounce </span>
<span>or </span>
<span>68 cents per ounce</span>
It’s b because it has more marbles

Lin
Step-by-step explanation:
5/7*2/2=10/14
3/2*7/7=21/14
10/14+21/14=31/14
