Step-by-step explanation:
A. One book =$9.25÷b
=$9.25/b
B.One pen=$1.30÷p
=$1.30/p
C. One book+One book
=[($9.25÷b)+($1.30÷p)]÷($9.25+$1.30)
=[(&9.25/b)+($1.30/p)]/($10.55)
 
        
             
        
        
        
Every millimeter is 1/10 of a centimeter, so 1 mm = 0.1 cm and 50 mm = 5 cm. This means that 25 mm can be re-written as 2.5 cm, and we can then find the difference by doing 25 - 2.5 = 22.5 cm. If you were looking for a different type of answer, you can also say that 25 mm is 10 times less than 25 cm.
I hope this helps!
        
                    
             
        
        
        
<span>Phil and Matt made cookies for a fundraiser at their high school. Phil worked more than Matt. Phil production was 25% more than Matt production. Matt was behind on the quantity made by Phil. The cookies sold for $0.25 each. After the sale, 20% of the combined production of their cookies remained.</span>
        
             
        
        
        
Well, to get perimeter, you add the length and width, and then multiply your answer by two. So:
Jerry- 
13+12=25
25*2=50
Ruth-
14+11=25
25*2=50
So both rooms are equal.
Hope this helps!!
 
        
             
        
        
        
The area of the poster is 216 inches.
The formula for the area of a parallelogram is a=bh (area=base•height).
so a = 12 • 18
a = 216 inches
