Answer:
625
Step-by-step explanation:
25x25 can be broken down into 20 x 25 and 5 x 25
20 x 25 is 10 x 25 x 2
10 x 25 is 250 and 250 times 2 is 500
25 x 5 is 125.
500+125 is 625.
The Answer Is 12X + 28 Because 4times3X Is 12X And 7times4 is 28
Answer:
books.
Step-by-step explanation:
We have been given that Hannah's school hosted a book donation.
Total number of students = 150.
Total number of books donated by all students = b.
Since we know that average is calculated by dividing the sum of the values in the set by their number.
Since we are told that Hannah donated 3 times as many as the average number of books each student donated. So books donated by Hannah will be:
Upon simplifying we will get,
Therefore, Hannah donated books.
