Jim and jon are painting a fence. jon painted 1/4 of the fence. jim painted 5/12 of the fence. how much of the fence did they paint in total?

2/3 of the fence

Step-by-step explanation:

Jim painted 1/4 of the fence

Jon painted 5/12 of the fence

Together they painted

1/4+5/12 of the fence

We need a common denominator to add the fractions

The common denominator is 12

1/4*3/3 + 5/12

3/12 + 5/12

8/12

This can be simplified by dividing the top and bottom by 4

2/3

Together, they painted 2/3 of the fence.

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
