In the form
ax+by=c
the slope is -a/b
to be paralell, itmust have the same slope
so an equation in the form 3x-2y=c is the answer
or anything where the whole thing is multiplied by the same number lke 2
6x-4y=8 for example
or it could be in slope inercept form
y=3/2x+b
Lengths of corresponding sides of similar polygons are in proportion.
That means that 2 is to 3 as 7 is to x where x is the length of the side of the other
triangle.
2/3= 7/x
2x = 21
x = 21/2 = 10 1/2
Answer: b) 10 1/2
The Probability that Robert randomly pulls out a black sock is 1/5 .
In the question ,
it is given that
Total number of socks in sock drawer = 30 socks
number of white socks in the drawer = 16 socks
number of black socks in the drawer = 6 socks
number of red socks in the drawer = 2 socks
number of yellow socks in the drawer = 6 socks
So , the probability that he randomly pulls out a black sock = (number of black socks in the drawer) / ( total number of socks in the drawer )
= 6 / 30
= 1/5
Therefore , The Probability that Robert randomly pulls out a black sock is 1/5 .

The skateboard costs $150. You can simply multiply the $30 by 5, since 100%/20%=5. To check, you can multiply $150 by .2 (20%), which comes out to $30.
