First you'd subtract .58 from 2.23 to get the price of the notebook.
2.23 - .58 = 1.65
(2.23×2)+1.65= 6.11
Now subtract 6.11 from ten to figure out the change amount.
10 - 6.11 = 3.89
Answer:
3 plus 2 is 5 so the answer is 5 hours
(x-4)(x-3) so what you do is
x -4
x x^2 -4x
-3 -3x 12
x^2-7x+12
your answer would be -7x
|-6 1/2|, |-1|, |0|, |9|, these are simply going from smallest to largest, once you get past 0 on a number line it goes back by one, for example 0,-1,-2,-3 and so forth, don’t think of negatives like whole numbers
