Hey there! :D
There is an additional charge for each topping.
$16= 1-topping pizza with basic charge.
$20= 3-topping pizza with basic charge.
The difference is:
20-16= 4 (the difference between the one topping and three topping pizza)
4/2=2 <== the price for each topping (divide the difference of toppings)
So, 16-2= 14 <== basic charge.
Price for 5-topping pizza:
14 (basic charge)+ 2(5)
14+10
24
The 5-topping pizza is $24 dollars.
I hope this helps!

Answer:
1/2, 2/4,& 3/6
Step-by-step explanation:
Well, two-twelfths plus four-twelfths is equal to size-twelfths which is equal to one half. Using this we can figure out which other fractions are equal to one half and answer the problem.

is the answer thanks
give me the brainliest pls
As soon as I read this, the words "law of cosines" popped
into my head. I don't have a good intuitive feeling for the
law of cosines, but I went and looked it up (you probably
could have done that), and I found that it's exactly what
you need for this problem.
The "law of cosines" relates the lengths of the sides of any
triangle to the cosine of one of its angles ... just what we need,
since we know all the sides, and we want to find one of the angles.
To find angle-B, the law of cosines says
b² = a² + c² - 2 a c cosine(B)
B = angle-B
b = the side opposite angle-B = 1.4
a, c = the other 2 sides = 1 and 1.9
(1.4)² = (1)² + (1.9)² - (2 x 1 x 1.9) cos(B)
1.96 = (1) + (3.61) - (3.8) cos(B)
Add 3.8 cos(B) from each side:
1.96 + 3.8 cos(B) = 4.61
Subtract 1.96 from each side:
3.8 cos(B) = 2.65
Divide each side by 3.8 :
cos(B) = 0.69737 (rounded)
Whipping out the
trusty calculator:
B = the angle whose cosine is 0.69737
= 45.784° .
Now, for the first time, I'll take a deep breath, then hold it
while I look back at the question and see whether this is
anywhere near one of the choices ...
By gosh ! Choice 'B' is 45.8° ! yay !
I'll bet that's it !
12 ÷ 3 - 5(12) + 4(12 - 2)
= 4 - 60 + 4(10)
= -56 +40
= -16
