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
Answer:
anything that ends in 0 like .10
Hold on i believe its C but let me go look on google and i'll get back to you to sure
Oh these are easy, I’ll explain.
To start off, the answer is 11.
I got this by subtracting DE (57) and BC (35). You get 22. Then, you divide the result of the subtraction by 2, which is 11.
Let me know if you need me to explain in more depth, and give brainliest if I’m correct tysm.
