<span>The book has sold 442,696 copies to date.
This was calculated by making a proportion: 8.9 : 39,400 = 100 : X where X Is the number of copies sold.
Then I calculated 39,400*100/8.9 to obtain the answer</span>
Answer:
Step-by-step explanation:
The linear equation in standard form is written in the form :
ax + by = c
Therefore : 12x = -9y + 7 in standard form will be :
12x + 9y = 7
It would not make sense if you were to do
34
28
The right way is
34
28
Another example is that if you were to subtract by 1 digit by 2
78
1
This is the wrong one

Petra is 13 and her mother is 32. I used this equation:
if you solve for p, you get 13. 13 times 2 plus 6 equals 32. So her mother is 32.
The expression simplifies to 6x^(28/5)
hope this helps :)
