As far as I know 0 IS a rational number. The only ones that are not rational are negative numbers. :) Though I could be wrong.....
Answer:
8 + 1.5x + 0.75y = pizza_cost
Step-by-step explanation:
It is given that every 10-inch cheese pizza costs ($8), meaning that this will be the constant.
Let (x) represent the number of inches added to the pizza. Since each extra additional inch costs ($1.5) thus one adds (1.5x) to the equation.
Let (y) represent the number of toppings. Every extra topping costs ($0.75) therefore one has to add (0.75y) to the equation.
Putting all of the elements together one gets the equation,
8 + 1.5x + 0.75y
5 2/3 - 1 1/4
5-2 =3
2/3 - 1/4 = 8/12 - 3/12 = 5/12
answer is 3 5/12
The answer is c
the 1st high school has 4 vans so 4v and 2 busses so 2b and as a total they have 112 students so then you get the equation 4v+2b=112
the next high school has 6 vans so 6v and 3 busses so 3b with a total of 168 students so then you get the equation 6v+3b=168
Answer: 5/2, 2.71, 2 3/4 , 5
