Step-by-step explanation: graph both equations where they intersect is the answer write it like this (x,y) the x and the y should be replaced with the numbers you'll get when they intersect. So if they intersected the point where they did if the y is 1 and x is 2 then the answer is (2,1). If they don't intersect at all and are parallel then it is no solution. If your only graphing one line which you aren't in this case but if you were it would be infinitely many.
I think the answer is B. Hope I helped a little :)
Answer:
29: 7
Step-by-step explanation:
![\frac{8}{3x - y} = \frac{5}{x + 3y}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B3x%20-%20y%7D%20%20%3D%20%20%5Cfrac%7B5%7D%7Bx%20%2B%203y%7D%20)
<em>Cross</em><em> </em><em>multiply</em><em>:</em>
![8(x + 3y) = 5(3x - y)](https://tex.z-dn.net/?f=8%28x%20%2B%203y%29%20%3D%205%283x%20-%20y%29)
<em>Expand</em><em> </em><em>bracket</em><em>:</em>
![8x + 24y = 15x - 5y](https://tex.z-dn.net/?f=8x%20%2B%2024y%20%3D%2015x%20-%205y)
<em>Bring</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>y</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>
![15x - 8x = 24y + 5y](https://tex.z-dn.net/?f=15x%20-%208x%20%3D%2024y%20%2B%205y)
<em>Simplify</em><em>:</em>
<em>
</em>
<em>Divide</em><em> </em><em>by</em><em> </em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
![x = \frac{29}{7} y](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B29%7D%7B7%7D%20y)
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>y</em><em>:</em>
<em>
</em>
∴ The ratio of x to y is 29:7.

Should be right
Answer:
There was 40 pizza slices total
Step-by-step explanation:
<u>Step 1: Make an equation to represent the situation</u>
10 people and each person get 4 slices
10 * 4 = p
<u>Step 2: Multiply</u>
10 * 4 = p
<em>40 = p</em>
<em />
Answer: There was 40 pizza slices total
