Answer:
4+(-6)+8+(-1)
Step-by-step explanation:
if she starts off at 4 points and her first turn she cuts 6 trees then you can add a negative 6 which is the same as subtracting that 6 when she plants 8 add those points then for her last turn add a negative 1 which is the same as subtracting 1 and she should end up with 5 points.
In order to make the whole problem easier, you would have to get all the numbers to have the same denominator which would be 60.
1/10 * 6 = 6/60
1/4 * 15 = 15/60
1/5 * 12 = 12/60
2/15 * 4 = 8/60
Now that all the numbers have the same denominator, you would add them to get 41/60.
In conclusion, the answer would be D.
Answer:
K=3.5
Step-by-step explanation:
1. y/x=k
2. 7/2 or
( 3.5 )
3. 10.5/3 or divided by 3 is 3.5
4. Continue divided y/x and if you get same answer than your constant of proportionality is 3.5 only for this question.
Find the number of groups of 3 potatoes there are:
9 potatoes / 3 = 3
For each group of 3 you need 1/4 teaspoon, so now multiply 1/4 by 3:
1/4 x 3 = 3/4 teaspoons are needed.
The answer would be C because they say if 3 new students arrived each year.
