These things be really confusing me a unit someone explain
Answer:C
Step-by-step explanation:
C
If you look at the top of the rectangle, you will see that 11 is half of 22.
22/11= 2
All you need to do is multiply 9 *2 for x.
9*2= 18.
I hope this helps!
Brainliest answer is always appreciated!<span />

Answer:
a = -6/5
Step-by-step explanation:
For the graphs to be parallel the graphs should have same slope(m)
So we rewrite both our equations in the slope-intercept form then compare the slope to find the value of a like this,
This equation is the slope-intercept form we convert both our equations in this form firstly taking equation 1
![5y=-2x+10\\\\y=\frac{-2x+10}{5} \\\\y=\frac{-2}{5}x+\frac{10}{5} \\\\y=\frac{-2}{5}x+2](https://tex.z-dn.net/?f=5y%3D-2x%2B10%5C%5C%5C%5Cy%3D%5Cfrac%7B-2x%2B10%7D%7B5%7D%20%5C%5C%5C%5Cy%3D%5Cfrac%7B-2%7D%7B5%7Dx%2B%5Cfrac%7B10%7D%7B5%7D%20%5C%5C%5C%5Cy%3D%5Cfrac%7B-2%7D%7B5%7Dx%2B2)
so if we compare it with y = mx + b the coefficient of x is m and hence
m= -2/5 now solving for equation 2
![3y=ax-15\\\\y=\frac{ax-15}{3} \\\\y=\frac{ax}{3}-\frac{15}{3} \\\\y=\frac{a}{3}x-5\\\\](https://tex.z-dn.net/?f=3y%3Dax-15%5C%5C%5C%5Cy%3D%5Cfrac%7Bax-15%7D%7B3%7D%20%5C%5C%5C%5Cy%3D%5Cfrac%7Bax%7D%7B3%7D-%5Cfrac%7B15%7D%7B3%7D%20%20%5C%5C%5C%5Cy%3D%5Cfrac%7Ba%7D%7B3%7Dx-5%5C%5C%5C%5C)
so here if we compare it with y = mx + b the coeffienct of x is a/3 so since parallel lines have same slope by the formula:
![m_1=m_2](https://tex.z-dn.net/?f=m_1%3Dm_2)
we equation both the slope to each other to find the value of a like this,
![m_1=m_2\\\\\frac{-2}{5}=\frac{a}{3}\\\\-2(3)=a(5)\\\\-6=5a\\-6/5=a](https://tex.z-dn.net/?f=m_1%3Dm_2%5C%5C%5C%5C%5Cfrac%7B-2%7D%7B5%7D%3D%5Cfrac%7Ba%7D%7B3%7D%5C%5C%5C%5C-2%283%29%3Da%285%29%5C%5C%5C%5C-6%3D5a%5C%5C-6%2F5%3Da)
so the value of a equals
a= -6/5
