Unit rates is the rate of a quantity in comparison to 1 i.e. unit.
Based on the given parameters, Shanya is the fastest typist
From the question, the unit rates are given as:
- James: 0.5 words per second
- Shanya = 3 words per seconds
The unit rates of Tristan and Ebony are not given.
So, we compare the rates of James and Shanya
3 words in a second is greater than 0.5 words in a second.
Hence, Shanya is the fastest typist

subtract the numbers:


subtract 9 from both sides

simplify

divide both sides by 6


decimal

Hope this helps :)
She is incorrect cause if we take the number 20 and take 25% of it it equals 5 so now 20 is only 15. They if we take 75% away from 20 is equals 15 so then we only have 5 from 20 left. Therefore she’s incorrect because 75% leaves 5/20 and 25% leaves 15/20. Hope that makes sense.
Answer:
$51.2
Step-by-step explanation:
If you subtract 64 to 20% then you end up with $51.2
B is just the y-intercept or where the line goes over the y axis so it would be 50
