1page and 3/7 of a page means 10/7pages.
2/3 minutes equals 40 seconds.
1 minute = 60 seconds
divide 10/7 by 40 then multiply the answer by 60 you get the number of pages Charlie can read per minutes.
(10/7 ÷ 40)*60=15/7=2 pages and 1/7 of the page.
Answer: 2 1/7
Answer:
3k -10
Step-by-step explanation:
8k - 6 -5k -4 = (8-5)k -(6+4) = 3k -10
Numbers 1 and 2 are correct.
Question 3:
We can see in each figure, the number of rows matches the figure amount. For example, figure 1 has 1 row, figure 2 has 2 rows, figure 3 has 3 rows, etc. Another thing we can see is that one block gets added to each column in every figure. If we count starting from 3 and keep adding 1 for each column, we get 22 blocks for one column. In figure 20, there will be 20 rows and 22 columns. We also have to keep in mind that they add 2 extra blocks at the top and bottom that stick out like the ones shown. In total, figure 20 will consist of 442 blocks.
Question 4:
[(2 + f) * (f)] + 2 = b
(2 + f) represents the number of blocks in each column.
(f) represents the number of blocks in each row.
2 represents the two extra blocks in each figure.
Note that f in this equation equals the number of the figure. For example, figure 3 is f = 3
We can test our equation with figure three.
[(2 + f) * (f)] + 2 = b
We have figure three so f = 3. Substitute and solve.
[(2 + 3) * (3)] + 2 = b
[5 * 3] + 2 = b
15 + 2 = b
17 = b
In the example, the number of blocks is 17. Therefore, this equation works for any figure.
Best of Luck!

The correct answer is: [D]:
___________________________________________
" three and twenty-eight hundredths ; 3 + 0.2 + 0.08 " .
___________________________________________
Note: Given: "3.28" .
_________________________
3
+ 0.2
0.08
____________
3.28 ;
___________________________
Note: The whole number, "3" (three);
"twenty-eight hundredths" = 28/100 = 28 ÷ 100 = 0.28 ;
___________________________________________________
Note: 0.2 = 2/10 = 20/100 = 20÷100 = 0.20 = 0.2 ;
___________________________________________________
Note: 0.08 = 8/100 = 8÷100 = 0.08 ;
