Answer:

Step-by-step explanation:
In representing mixed numbers on a number line, we need first to pay attention to the denominators. Here, denominators are 8 and 5, their least common multiple is 40, so, we will need to cut up space between two numbers on the number line on 40 pieces. Also, we have 5 and 3 wholes at these mixed numbers, so, our answer is going to be greater than 8.
We will cut the space between 8 and 9 on a number line on 40 pieces, and we will add
and
and get :

So, on a number line between 8 and 9 we need to count 31 out of 40 pieces and that is the result, 8 wholes and
.
Answer:
openup 1 em We want to find the points on the curve y=2x^3-3x^2-12x+20y where the tangent line is parallel to the xx-axis, which means that the slope=0
The answer is D (i have to type at least 20 letters soooooooooo)
The 2 in 2341 represents 20,000
meanwhile the 2 in 1234 represents 200 so the 2 in 2341 is 10 times great.
I hope this helps
