A12-inch cheese pizza at neighborhood pizza costs $9.95 and each additional topping is $1.00. the same size pizza at downtown pizza costs $6.95 and each additional topping is $1.50. at how many toppings do the pizzas cost the same? 6 toppings 5 toppings 4 toppings 5.5 toppings

Let us write an equations 

1st pizza place costs 9.95 + x dollars, where x is the number of toppings 
2nd pizza place 6.95 + 1.5 y dollars, where y is the number of toppings

We are interested when they are equal: 

9.95 + x = 6.95 + 1.5y
3= 1.5y - x
As the questions asks for the same ammount of toppings, x=y

3= 1.5y - x this becames
3=0.5 x
x=6

Lets check 
9.95+6=15.95
6.95+6*1.5=15.95 

So the answers is 6

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
