Answer:
They should use <u>1.2 gallons</u> of yellow paint.
Step-by-step explanation:
Given:
Julia and Rasheed are mixing yellow paint and blue paint to make green paint.
The mixture needs to be 60% blue paint and 40% yellow paint.
They need to make 3 gallons of the green paint.
Now, to find the quantity of yellow paint they should use.
As,
60% + 40% = 100%
So, we get the ratio of blue paint to yellow paint:
= 
= 
= 
Thus, the ratio of blue paint : yellow paint is 3:2.
<em>They need to make total 3 gallons of green paint.</em>
Now, to get the quantity of yellow paint:
Therefore, they should use 1.2 gallons of yellow paint.
Step-by-step explanation:
the slope is always the factor of x.
it is expressed as ratio y/x indicating how many units y changes when x changes a certain amount of units.
parallel means they have the same slope (factor of x).
perpendicular (90 degrees) means x and y trade places upside-down, and the sign is flipped.
so,
10) neither. we have the slopes -2/1 and 1/1.
11) parallel. the slopes -1/2 and -1/2.
12) perpendicular. the slopes 5/1 and -1/5.
16) parallel. special case. all points that have x=4 and x=2. these are 2 vertical lines (parallel to the y-axis also known as x=0).
17) perpendicular. special cases. all points that have y=2 and all points that have x=5. this is one horizontal line and one vertical line, which makes them perpendicular.

Since the equations are the same, the answer is infinitely many solutions.
Final answer: Infinitely many solutions
