The answer to this would be 3/8.
you just simplify the given terms, so -1 7/8 can be simplified into -15/8 and 2 1/4 can be simplified into 9/4, add those together to get a sum of 3 over 8 or 3/8.
Good Luck
Answer:
1. False
2. True
3. True
4. True
5. False
Step-by-step explanation:
1. False - they sell 3 cases in 20 min as shown in the table
2. True - If they sold 3 cases in 20 min and 6 cases in 40 min, then they would sell 9 cases in an hour, and 12 cases in 1 hour and 20 min
3. True - Building off of our answer in 2, student council would have sold 15 cases in 1 hour and 40 min, and 18 in 2 hours
4. True - In 40 min, student council sold 6 cases, and in 2 hours, 18 cases, so in 2 hours and 40 min, they would have sold 24 cases
5. False - In one hour - 9 cases. In 2 hours - 18 cases. In 3 hours - 27. And in 20 min - 3 cases, so they would sell 30 cases in 3 hours and 20 min.
Answer: 1.6 lawns a week
Step-by-step explanation:
Carlt mowed 2 more lawns than Rocco every week for 5 weeks.
This means that the number of lawns he mowed more than Rocco is:
= 2 * 5
= 10 lawns
If Carlt mowed 18 lawns in those 5 weeks then Rocco mowed:
= 18 - 10
= 8 lawns
Lawns mowed per week by Rocco:
= 8/5
= 1.6 lawns a week
With negatives included, no.
You can add a negative with a positive and get a lesser number than you would when subtracting, only if you subtract the negative from the positive, making it become addition.
1 + (-1) = 0, while 1 - (-1) = 2. Some more examples are 3 and -8, 4 and -1.
Hope this helps! :)
