Answer:
Mitochondria is the powerhouse of the cell
Step-by-step explanation:
The correct answer is A. 10
8 divided by 0.8 = 10
10x0.8=8
9(2w−y)=21w−9y
First you multiply the numbers in the parenthesis by 9

subtract. 21w-18w=3w

add. -9y+9y=0

divide.

Final answer is 0.
Answer:
9 tens = 90
5 hundreds = 500
3 ones = 3
on adding them we get, 500 + 90 + 3 = 593
