Step-by-step explanation: When ordering pizzas there will be an initial fee, followed by the cost per pizza. Call the initial fee f and the cost per pizza p, and you get for the second and first equation respectively; 5p+f=49; 3p+f=33; you subtract these in that order and you get 2p=16 so p =8!

13.
1st: split the 1 shape into 2 shapes. (spit across to where you see one right angle(top), and a trapezoid(bottom)
2nd: now what i did was fill that gap to where the total height is 9 and the total length is 7. ( if you don't want to do that it is fine )
3rd: for the top do 5 times 2 = 10
4th: for the bottom do 4 times 5 = 20
5th: add 10 (top) and 20 (bottom) = 30
1:4. 16 is 25% of 64, or 1/4, this translates to 1:4 in ratio form.
