Answer:
7 to 3 is this answer
Step-by-step explanation:
if you noticed, with all the other ones they all have 3 : 7 in it. So by the process of elimination it's 7 to 3 that is different. I'll tell you why,
3 : 7, that is the ratio we have as an example. That's why it isn't the different one.
3 to 7, you say 3 : 7 as 3 to 7 to it still has the same ratio
3/7, this is how to type the fraction version of the ratio so it makes sense that it is the same one as 3 : 7.
7 to 3, if you haven't noticed yet, all of them has 3 : 7 as a counterpart. They are all the same but this one, this is 7 : 3 or 7 to 3. So with logic, this is the different ratio.
<h3><u>The value of x is equal to -4.076</u></h3><h3><u>The value of y is equal to 5.057</u></h3>
3x + 4y = 8
7x - 8y = -69
<em><u>To make this easier, we can multiply each term in the first equation by 2.</u></em>
6x + 8y = 16
Now, we can use elimination to isolate one variable.
<em><u>Combine equations.</u></em>
13x = -53
<em><u>Divide both sides by 13.</u></em>
x = -4.076
We can plug this value of x into the equation to find the value of y.
3(-4.076) + 4y = 8
-12.228 + 4y = 8
<em><u>Add 12.228 to both sides.</u></em>
<em><u>4y = 20.228</u></em>
Divide both sides by 4.
y = 5.057
The answer is 2/3... I hope this helped
