Sara ordered 2 slices of pizza and a 12-ounce cola and paid

Natasha_Volkova [10]

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Step-by-step explanation:

Let slice of pizza cost x and a 12-ounce cola cost y.

Then Sara's order cost: 2x+y=3

and Sydney's order cost: 3x+2y=4.75

From the first equation we have: y=3-2x and put this to the second equation:

3x+2(3-2x)=4.75

3x+6-4x=4.75

x=1.25

y=3-1.25*2=0.50

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Use five different colors to paint the four rectangles A, B, C and D shown in the figure. No two rectangles sharing an edge can

GenaCL600 [577]

There are 120 ways to color the 4 rectangles

<h3>How to determine the number of ways?</h3>

The given parameters are:

Paints, n = 5

Rectangles, = 4

The number of ways to color the rectangles is

$Ways = ^nP_r$

This gives

$Ways = ^5P_4$

Apply the permutation formula

$Ways = \frac{5!}{1!}$

Evaluate the expression

Ways = 120

Hence, there are 120 ways to color the 4 rectangles
