First, simplify 3/12 into 1/4 find the least common denominator which is 20
then, 18/20 by 5/20 will equal 13/20.
Answer:
2 is the correct answer.
Step-by-step explanation:

Answer:
35 red marbles
Step-by-step explanation:
So we can put the different color marbles in a ratio. So 7:2:11. If we add all of those up we get 20. We do 100/20 to get 5. Each number in the ratio is equivalent to 5 marbles. Then we do 7*5 to get 35. We can check our work by doing, (7*5) + (2*5) + (11*5) = 100. And it does equal 100 so the answer is correct.
Answer:

That is the slopes of AB, BC, CD and AD are equal
Note that y = x has a slope of 1
Thus the slopes between any of the points is 1
