Carlos read 144 pages in 3 hours. His little sister read 24 pages in 1 hour. carlos's average reading rate is what percent of hi
ehidna [41]
Hello! So Carlos' sister reads an average of 24 pages in 1 hour. He reads 144 pages in 3 hours. To find the unit rate Carlos reads, let's do some division. 144/3 is 48. Carlos reads an average of 48 pages in 1 hour. If you use mental math, 48 is double the amount of 24. 200% is just simply 2. 24 * 2 is 48. D is the only one that shows an answer that even fits for this scenario. Carlos' average reading rate is 200% of his sister's. The answer is D: 200%.

D₁ vide using x² - 2x² 2× +3× -5 by ×-3 using synthetic division. <br>​
Vaselesa [24]

Answer:

Step-by-step explanation:

I think you are trying to use synthetic division for

x^{4} -2x^{3} -2x^{2} +3x-5 divided by x-3

First  

x -3 = 0 , make it equal to 0 and add 3 to both sides

x = 3

Then we write all the coefficients and continue with

a pattern of multiply by 3 and add to the next coefficient.
