The backdrop is taped off into 12 equal sections for the students to paint. ​

​Mark paints 2 times as much as Jill.

Sam paints 3 times as much as Lou.

Lou paints 1 section less than Mark.

Jill paints 1/12 of the backdrop

What fraction of the backdrop still needs to be painted

​

5/12

Step-by-step explanation:

Jill 1/12

Mark 2/12

Lou 1/12

Sam 3/12

add them together

7/12

12-7=5

5/12

8121 because

130,000 divided by 16 is 8121

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
