Answer:
2*16n = 21 -7n
Step-by-step explanation:
hope this helps :)
top:
(2x - 3y)^2
= 4x^2 - 12xy + 9y^2
bottom:
(3y - 2x)^2
= 9y^2 - 12xy + 4x^2
= 4x^2 - 12xy + 9y^2 (same as top)
so
(4x^2 - 12xy + 9y^2) / ( 4x^2 - 12xy + 9y^2) = 1
Ava is not correct. If you look at the denominator on her work:
[-(2x – 3y)]^2
= [(-1 )(2x – 3y)]^2
= (-1)^2 (2x – 3y)^2
= (2x – 3y)^2
so (2x – 3y)^2 / (2x – 3y)^2 = 1
The correct answer is 1
Corresponding angles are congruent.
x = 115
Answer:
She donated b/50 books
Step-by-step explanation:
In this question, we are we are told 150 students donated a total of b books. The average number of books donated by each student will be:
The total number of books/ the total number of students.
The average number of books is this b/150.
Now, we are also told that Hannah donated 3 times the average number of books.
This is simply calculated by multiplying the average number of books donated by 3
This is equal to 3 * b/150 = b/50 books
Hence, Hannah donated b/650 books
