Answer: 1, 3, both show a change in temp
That represents an easy direct division, we divide:
$22.85 / 17 boxes = 22.85/17
= 1.34 dollars per box of crayon
that is the cost
Find the ratio of two corresponding sides,
- if you start with the smaller figure, your answer will be less than one
- if you start with the larger figure, your answer will be greater than one
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
The area is 9.9 or 9 9/10
