Can someone please help me with number 13.

You can set up 2 equations for the two companies that sell pizza. Pizza A's will be:
y = 1.5x+10

And B's will be:
y = x+12.50

To find the number of toppings we will need to make the companies prices equal can be found by setting the equations equal to each other and solving for x, because x is the price per topping. So:
1.5x+10 = x+12.50
1.5x = x+2.50
0.5x = 2.50
x  =   \frac{2.5}{0.5}  = 5

So, the number of toppings you will need is 5 toppings to make their prices equal. 

*If any step is unclear, then hmu!

<span>Which shows the elements of the set of whole number multiples of four less than 21?

The multiples of 4 are 4, 8, 12, 16, 20, 24, 28,...

Then, the set of the multiples of four less than 21 is {4, 8, 12, 16, 20}

A: {1, 2, 3, 4, 5}
B: {4, 8, 12, 16, 20}
C: all real numbers
D: null set

Which shows the set(s) the number 2.77 is an element of?

2.77 is a real number, it is not a natural number, and it is not a whole number.

A: real numbers

B: real numbers and natural numbers

C: natural numbers and whole numbers

D: null set


Given sets:

D = {5, 6, 7, 8, 9, 10}, E = {1, 3, 5, 7, 9, 11}, F = {3, 6, 9, 12}

What is D n E?

I believe the question is what is D ∩ E, which is the elements that are as much in D as in E. This is {5,7,9}

A: {1, 3, 5, 6, 7, 8, 9, 10, 11}

B: {5, 7, 9}

C: {9}

D: null set</span>
