A=1/2bh
1st step: Multiply both sides by 2
2A=bh
2nd step: Divide both sides by h
2A/h=b
The equation is used to find the area of a triangle. The problem is asking to use this formula to find the formula to find the height of a triangle.
b=base of the triangle
h= height of the triangle
A= Area of the traingle
Although, if other geometry based problems use these problems it's just base and height and Area.
Alex is correct the book would cost $18.52 before taxes adding 10% tax the book would cost an additional $1.85 for a total of $20.37. This would be just under the $21.00 that both Alex and Laura had to spend. Laura tried to combined the 35% discount which you cannot do. So yes they both would be able to purchase the book.
Given:
adults = x
male = 7x + 1
female = (7x + 1)/2
total number of people = 82
x + (7x + 1) + [(7x +1)/2] = 82
2x/2 + (14x + 2)/2 + (7x + 1)/2 = 82
2x + 14x + 2 + 7x + 1 = 82 * 2
23x + 3 = 164
23x = 164 - 3
23x = 161
x = 161/23
x = 7
adults = x = 7
males = 7x + 1 = 7(7) + 1 = 49 + 1 = 50
females = (7x+1)/2 = 50/2 = 25
7 + 50 + 25 = 82
