Answer:
2x - 0.4x ;
8x/5 ;
Yes
Step-by-step explanation:
Let number of miles = x
Arlene:
Double number of miles = 2 * x = 2x
Subtract 20% of the result :
2x - 20% of 2x ;
2x - 0.4x
Raul:
Divides Number of miles by 5 ; x / 5
Multiplies result by 8 ;
8 * (x/5) = 8x /5
To know if expressions are equivalent :
Let x = 10 miles
Using Arlene's expression:
2x - 0.4x
x = 10
2(10) - 0.4(10) = 16
Using Raul's expression :
8x / 5
(8*10) / 5
80/5
= 16
Since they give the same result, we can conclude that the expression are equivalent
<h3>Given</h3>

<h3>Find</h3>

<h3>Solution</h3>

The derivative of the average cost function at n=10 is -0.30.
Answer:
No, they are not equivalent.
Step-by-step explanation:
There are two ways to check this.
1. You can multiply the means and extremes. If the ratios are equivalent, they products of the means and extremes will be equal.
Multiply the means (2 and 7) and multiply the extremes (6 and 3)
14 ≠ 18
2. You could also check these by dividing them.
6/2 = 7/3
3 ≠ 2.3
Since neither one of the checks are correct, 6:2 and 7:3 are not equivalent.
I really hope this helps =)
