(9 + 1) + (9 + 2) =
21 dollars
Answer:
Total cost for two pizzas = 21 dollars
Step-by-step explanation:
Price of plain pizza = 9 dollars.
Price of topping = 1 dollar
Number of pizzas ordered = 2
Price of pepperoni pizza = 9 + 1 = 10 dollars.
Price of mushroom and pepper pizza = 9 + 2 = 11 dollars.
Total cost of 2 pizzas = 10 + 11 = 21 dollars
75 X 3000 = 225000
225000 + 50000 = 275000
275000 - 270000 = 5000

Senior citizen tickets = $9
Student tickets = $11
We begin by converting these into simultaneous linear equation;
Senior citizen tickets = a
Student tickets = b
5a + 9b = 144
14a + 6b = 192
5a = 144 - 9b
a = 144/5 - 9b/5
a = 28.8 - 1.8b
We now substitute this into the first equation
14(28.8 - 1.8b) + 6b = 192
403.2 - 25.2b +6b = 192
-19.2b = 192 - 403.2
b = -211.2/-19.2
b = 11
Put the value of b into either equation
5a + 9(11) = 144
5a +99 = 144
5a = 144-99
5a = 45
a = 9
1. Answer is 162 2. Answer is 159.2
In the first one we calculate both triangles by using and multiply it by 2 since we have 2 triangles
then we calculate the rectangle
and then we put them all together and get the answer which is 162.
in the second one we calculate the trapezoid then rhombus, then we put them together and get our answer which is 159.2
Answer: 102,400,000,000,000,000,000
First do 20^10 = 10,240,000,000,000.
Then, multiply 10,240,000,000,000 * 10,000,000 to get 102,400,000,000,000,000,000.
