Answer:
The slope is 3
Step-by-step explanation:
Parallel lines always have the same slopes. This equation is in slope-intercept form, y=mx+b, m being the slope. Our m, or the slope, is 3, and because the line is parallel, it also has a slope of 3.
Answer:
Step-by-step explanation:
Total marbles are 212
112/212 = 28/53
Approx. 52. 83%
To solve this problem you must apply the proccedure shown below:
1. You have the following points given in the problem above:

2. To find the midpoint, you must apply the formula that is used for calculate it. This is:

Where:

3. Now, you must substitute these values into the formula for calculate the midpoint, as following:

Therefore, the answer is: 
2 months, 600 x2 = 1200+1000 =2200
850 x2 = 1700+500 = 2200
