You find the unit rate of the books by dividing the number of books by the that price, and for this example the answer should be $.75 per book
Subtract $3 from $21 to get the cost of skating for three hours without the rental fee. 21-3=18. $18 was spent on skating for three hours so you'll divide 18 by 3 to get the hourly rate. 18/3=6.
C(x)=6x+3
Answer:
(X-2)(x+y)
Step-by-step explanation:
So we can factor X out, x(x-2) and factor y out y(x-2). Now we can factor out the x-2, so we have (x-2)(x+y)
Step-by-step explanation:
The question missing attachment (incomplete)
But the question said how far up does the ladder reach on the building?
See the attachment
Let the tita be 60° and the height of the building be 50 meters
Now
Opposite/hypotenuse = sin(tita)
50/x = sin60°
Cross multiply to find x
x = 50/sin(60°)
x= 50/0.8660
x=57.7 meters
