Answer:
Mark's model is nonsense
Step-by-step explanation:
- Both Mark and Robyn used "based-ten blocks" to show that 200 is 100 times 2.
- Marks model shows 20 instead of 2.
- His model shows 200 is 10 times as much as 20. It does not make any sense.
- Robyn model shows 2 correctly, implicating 200 is 100 times as much as 2.
- Because,
2 * 100 = 200
So Mark's model is nonsense!

Step-by-step explanation:
5x-2 and 5x+2 are corresponding angles
They add up to 180 degrees
5x-2 + 5x + 2 = 180
10x = 180
x = 18
I hope this helps!!!
To answer this question you need to figure out how many groups of 2 quarts you can make from a total of 5 gallons. You will need to know the conversion of gallons to quarts. There are 4 quarts in each gallon, so you would have 5 groups (5 gallons) of 4 quarts. 1 gallon = 4 quarts, 2 gallons = 8 quarts, 3 gal = 12 qts, 4 gal = 16 qts, and 5 gal = 20 qts. This can be shown as 5 x 4 = 20 qts. Out of the 20 quarts you can make 10 groups of 2 quarts. This can be show as 20/2. You can fill the canteen 10 times.
