You suppose to make the equation add each other I pretty sure so it be A.
Answer: $27.85
Step-by-step explanation:
$5.25*7=$36.75
$36.75-$8.90=$27.85
For this case what we can do is the following rule of three:
6 hours ---> 36 bags.
x ------------> 1 bag
Clearing the value of x we have:
x = (1/36) * (6)
x = 6/36
x = 1/6 hours
Answer:
Assuming the bags are filled at a constant rate, the average time it takes to fill one bag of leaves is:
x = 1/6 hours
Answer:
-4
Step-by-step explanation:
The average rate of change of a function f(x) between two points x = a and x=b is given by,

This can be understood with a simpler example, the straight line.
In this case, the rate of change of the 'function' is given by the slope,
;
being two points on the straight line.
So, for the given problem,
a = -2
b = 2
Hence, average rate of change of 
6x-2>4x-6
2x-2>-6
2x>-4
X>_ -2
