You would represent the number of apples with the variable a.
So the equation for that word problem would be = a/12.
I hope you find this answer the most helpful! :)
The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
A = 1/2 bh can be written as
A = bh/2.
2A = (bh/2)(2)
2A = bh
Divide both sides by h to find b.
2A/h = b
Done.
