ANSWER
Lea can wash 4½ loads of laundry with the remaining detergent.
EXPLANATION
Quantity of detergent left
Quantity required to watch each load
Number of loads Lea can wash
We now simplify this by multiplying with the reciprocal
Number of loads Lea can wash
Therefore Lea can wash 4½ loads of laundry with the remaining detergent.
Answer: each book costs $13
Step-by-step explanation:
dividing 65 by 5 gets the answer
The mean absolute deviation of a set of data is the average distance between each data value and the mean.
The mean is (20+25+30+30+45)÷5=30
( |20-30|+|25-30|+|30-30|+|30-30|+|45-30| )÷5=6
The mean absolute deviation is 6.

Answer:
- f(x) = x
- g(x) = -2x+1
- f(x) -(-g(x)) = -x+1
- f(x) +g(x) = -x+1
- f(x)-(-g(x)) = (f+g)(x) is true for all functions f and g, linear or not
Step-by-step explanation:
We can define a couple of linear functions as ...
f(x) = x
g(x) = -2x+1
Then the reflected function -g(x) is ...
-g(x) = -(-2x +1) = 2x -1
And the difference from f(x) is ...
f(x) -(-g(x)) = x -(2x -1) = -x +1 . . . . f(x) -(-g(x))
We want to compare that to the sum of the functions:
f(x) +g(x) = x +(-2x +1) = -x +1 . . . . f(x) +g(x)
The two versions of the function expression have the same value.
These results are <em>a property of addition</em>, so do not depend on the nature of f(x) or g(x). They will hold for every function.
