This is the last question on my
the cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t.
write an inequality that can be used to represent the cost of a pizza that is at most $12.
what is the most number of toppings that a pizza can have and still be at most $12?

answer:

at most there can be 5 toppings on the pizza.

step-by-step explanation:

first, we need to create our inequality.

we know that 9.99 is the static price, while 0.35 changes with the amount of toppings. this means that 0.35 must be accompianied by a t. next, we need to decide what kind of sign that we need. in this case, it needs to be at most 12. this means that it must be less than or equal to 12, so we will use the sign .

knowing all of this, we can create our inequality

now that we have our inequality, we can solve for t.

we need to keep in mind that we cannot have a decimal value for the number of toppings. this means that we have to round down to 5 toppings.

b. astronomers

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
