Let the number of sports drinks April bought be represented by = s

Let the pizza slices April bought be represented by = p

As she spent a total of $21.25 so equation becomes:

s+p=21.25

p+3+p=21.25

2p=18.25

p=9.125

As she bought 3 more sports drinks than pizza slices so, s = p+3

Answer:

Number of Sports drinks purchased is equal to 8

Step-by-step explanation:

Complete Question

April bought some sports drinks and slices of pizza for her friends. She bought 3 more sports drinks than slices of pizza. If her total order was 21.25, how many sports drinks did she purchase? one slice of pizza cost 2.25 and one sport drink cost 1.25

Solution -

Let the total number of slices of pizza's purchased be X

Then the total number of sports drinks purchased would be X + 3

Given -

Price of one slice of pizza = 2.25 dollars

Price of one sports drinks = 1.25 dollars

The total cost of X slices of pizza and X + 3 sports drinks would be

X * 2.25 + (X+3) * 1.25 = 21.25

2.25 X + 1.25 X + 3.75 = 21.25 \\3.5 X = 21.25 -3.75\\3.5 X = 17.5\\X = \frac{17.5}{3.5} \\X = 5

Thus, the number of slices of pizza purchased is equal to 5

Hence, number of Sports drinks purchased is equal to

5 + 3\\8

Marina86 [1]

Answer: \dfrac{1}{6840}

Step-by-step explanation:

According to the permutations:

The arrangement of n things in an order = n!

If we fix that the first, second, and third person for skating, then we to arrange only 17 of the skaters.

Number of ways to arrange rest of 17 skaters = 17!

Number of ways that Christie, Taylor, and Jona will  skate first, second, and third, respectively = 1 x 17!=17!

Number of ways to arrange all 20 skaters = 20!

Now, the required probability = \dfrac{\text{favourable outcomes}}{\text{total ways}}

=\dfrac{17!}{20!}\\\\=\dfrac{1}{20\times19\times18}\\\\=\dfrac{1}{6840}

Hence, the required probability = \dfrac{1}{6840}

Find the measures of x and y
Blizzard [7]

Answer:

x = 159; y = 140

Step-by-step explanation:

a = 40

a + y = 180

y = 180 - 40

y = 140

b = 61

b = (180 - x) + a

61 = 180 - x + 40

x = 159
