Step-by-step explanation:
let 1 pound of nail = x
so, the carved out waste nail will be = 12x
total nails = 13x
so the equation is =
13x - 12x = x
OR
x + 12x = 13x
Or
13x - x = 12x
Answer:
(4a - 3)(2x - 3)
Step-by-step explanation:
Answer:
<u>The three equations:</u>
- y = 15x, wolf
- y = 10x + 15, you
- y = 5x + 20, friend
<u>Compare the equations with wolf and you and with wolf and your friend:</u>
- 15x = 10x + 15
- 5x = 15
- x = 3 seconds
It will take 3 seconds before you are caught by the wolf
- 15x = 5x + 20
- 10x = 20
- x = 2 seconds
It will take 2 seconds before your friend is caught by the wolf, he will be caught a second before you.

If so, the answer is -5,333.
The sum of Heptagon’s inner angles is 180*(7-2)=900 degree
So x=900-146-122-142-140-110-142=98
