Answer:
The sum −3 is an indication that Sally is 3 feet below her initial position.
Step-by-step explanation:
Represent the distances going up (ascend) as positive and distances going down (descend) as negative so that the sum is:
224 + (-131) + 67+ (-163)
Add by using the commutative property:
224 + 67 + (-131) + (-163) = 291
The sum −3 is an indication that Sally is 3 feet below her initial position.
Answer:132 combinations
Step-by-step explanation:

Please consult the "Calculations" section of this ans .

The information we're given is below :
- slope : -1/3
- Point crossed by the line : (3, 6)
As per given information , we can do the following :
- Write the line's equation in point slope form
Point - slope form looks like so :
y-y₁=m(x-x₁)
y-6=-1/3(x-3)
y-6=-1/3x+1
y=-1/3x+1+7
y=-1/3x+6

7*24 = 168 quarts of water per day goes into barrel.
25*48 = 1200 quarts of waste water picked up
1200÷168 =7.142857143
5.21.
To find this, give both numbers decimal points before setting up a subtraction equation as so:
15.00 - 9.79
Then proceed to solve to get the final answer of 5.21.
Hope this helps!
