N = 4
(3)(4)-(2+4) = 12 - 6 = 6
2 1/2 is in mixed fraction. So let's first make it into improper fraction.
(2*2 + 1) / 2 = 5/2
5/2 of 7.25 = (5*7.25) / 2 = 18.125
in short, 18.125 is the answer
Answer:
The Answer is: There are 8 small boxes and 9 large boxes. See explanation below for variables and variable definitions.
Step-by-step explanation:
Let s = small boxes. Let b = large boxes.
s + b = 17
You can solve for s:
s = 17 - b
You can solve for b:
b = 17 - s
10 times the number of small boxes plus 24 times the number of large boxes is equal to 296 granola bars.
10s + 24b = 296
Substitute:
10(17 - b) + 24b = 296
170 - 10b + 24b = 296
14b = 296 - 170
14b = 126
b = 126 / 14 = 9 large boxes
Find the number of small boxes, s:
s = 17 - b = 17 - 9 = 8 small boxes
There are 8 small boxes and 9 large boxes.
Proof:
10(8) + 24(9) = 296
80 + 216 = 296
296 = 296
Area = b * h
Area of orange = area of big square subtract by area of small square
Small square = b^2
Big square = a^2
(a^2 - b^2) = (a - b)( a + b)
Solution: (a - b) (a + b)
