Answer:
The number of books are 189.
Step-by-step explanation:
ratio of note books to the books = 2 : 3
total notebooks = 126
Let the number of books is x.
So, the ratio is
![\frac{2}{3} = \frac{126}{x}\\\\x = 189](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20%3D%20%5Cfrac%7B126%7D%7Bx%7D%5C%5C%5C%5Cx%20%3D%20189)
So, the number of books are 189.

-3 degrees C
Answer:
x = -1
Step-by-step explanation:
5x + 2y = 1 (eqn 1)
y = -x + 2 (can also be written as y = 2 - x)
subbing y = -x +2 in eqn 1,
5x + 2(2-x) = 1
5x + 4 - 2x = 1
3x = 1 - 4
3x = -3
x = -1

If a toy that costs $2.99 is at a 30% discount then you first need to make 30% a decimal.
30% = .3
Now multiply $2.99 by .3 to find the discount which is .897
Since .897 has a thousandths place we need to round that which would make it 90 cents.
Now we know there is a 90 cent discount on a $2.99 toy.
take $2.99 - 90 cents = $2.09
The toy costs $2.09 after a 30% discount
