Answer:

10 dollars for each pizza

Step-by-step explanation:

100-20 is 80

80/8=10

I think your getting confused with The ice cream and soda part. If you think about it, it says AND which basically means together, if it said excluding it means not including so together ice cream and soda would be 20 dollars.

This question can be solved by a trigonometric equation. Shadow formed when something with height like a tree, so it can be pictured as a vertical line. Shadow is a length of and can be pictured as a horizontal line.  
In trigonometric, to find the vertical line length with horizontal line you need tan function. The sun angle will be used in the function, so the calculation would be: tan(31) x 42ft = 25.2361459992ft

If the total area of a picture measuring 10 inches by 12 inches plus a matting of uniform width surrounding the picture is 224 s
ELEN [110]
Let
x-----------> <span>uniform width surrounding the picture

we know that
(10+2x)*(12+2x)=224-----> 120+20x+24x+4x</span>²=224
4x²+44x+120-224=0
4x²+44x-104=0

using a graph tool-----> to resolve the second order equation
see  the attached figure

the solution is
x=2 in

the answer is
2 inches

I don’t understand, please help! Solve m=p/2-n for n.
belka [17]

Answer:    n=p/2-m

Step-by-step explanation:

m=p/2-n   (1)

Add n to both sides of the equation  (1)

m+n=p/2-n+n => m+n=p/2     (2)

Subtract m from both sides of the equation (2)

m-m+n=p/2-m => n=p/2-m
