Answer:
x= -7/5 y=8/5
Step-by-step explanation:
1. choose a variable to eliminate (i chose 6)
2. multiply the first equation by 2 and the second equation by 3
3. now you have
-6x+6y=18
6x-21y=-42
and the x's can now cancel out when you add the equations together
4. after adding the equations, you get
-15y=-24
5. solve for y (y= 8/5)
6. now plug in 8/5 for the y in one of the original equations to solve for x. (i chose the first one)
7. -3x+3(8/5)=9
-3x+24/5=9
-3x=21/5
x= -7/5

Answer:
![k=\frac{5}{4}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B5%7D%7B4%7D)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have that
The line pass through the points
<em>Find the value of the constant of proportionality k</em>
For x=2/5, y=1/2
substitute
![k=\frac{y}{x}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7By%7D%7Bx%7D)
![k=\frac{1}{2}:\frac{2}{5}=\frac{5}{4}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B1%7D%7B2%7D%3A%5Cfrac%7B2%7D%7B5%7D%3D%5Cfrac%7B5%7D%7B4%7D)
Does the weight matter? Anyways i think you’re basically doing multiplication which is 0.69 x 2 = 1.38.
