The roses were 20 dollars :) have a good day.
formula=1/3 x 3.14 x r^2 x height
=16 is diameter so radius will be 16/2 or 8
<em>:</em><em>let </em><em>put </em><em>terms </em><em>in </em><em>the </em><em>formula:</em>
1/3 x 3.14. x 8^2 x 15 = <em><u>1</u></em><em><u>0</u></em><em><u>0</u></em><em><u>4</u></em><em><u>.</u></em><em><u>8</u></em>

Let x = cost of one cheese pizza.
Let y = cost of one pepperoni pizza.
Set up a system of equations.
6x + 7y = 153.50
2x + 2y = 47.00.
Multiply the second equation by -3
6x + 7y = 153.50
-6x - 6y = -141.00.
Add the equations together
y = $12.00.
Plug 12 into one of our original equations.
2x + 2(12) = 47.
Simplify the left side.
2x + 24 = 47.
Subtract 24 from each side.
2x = 23.
Divide each side by 2
x = $11.50
In conclusion, one pepperoni pizza costs $12.00
1487.93 should be the correct answer I believe.
42 + 8x + 13 = 7
8x + 55 = 7
8x = 7 - 55 subtract both sides by 55
8x = -48
x = -48/8 divide both sides by 8
x = - 6
hope this helped, God bless!
