Answer:
ummmm
Step-by-step explanation:
Make each known side into a ratio like so...
75/6
(Because 75 is the shadow casted by the building, and 6 is the shadow casted by sarah)
and 50/x
(50 is how tall the building is and sarah's height is what needs to be found)
Therefore,
75 50
---- -----
6 x
Do cross products;
50 x 6 = 75 x X
300 = 75x
Divide by 75
x = 4ft
A solution to a equation is when the variable is substituted fully. That makes the equation true.
I am also not sure, because I also asked this question.
$9 + $7 + $5 = $21 so $18 - $21 = account balance = -$3
