Answer:

x = 5 pens

y = 7 pencils

Step-by-step explanation:

let

x = the number of pens

y = the number of pencils

Anthony spent $2.80 to buy a total of 12 pens and pencils

0.35x + 0.15y = 2.80

x + y = 12

by solving the system of equations

0.35x + 0.15y = 2.80

x + y = 12

we find

x = 5 pens

y = 7 pencils

Which equation shows an example of the associative property of addition?
Nat2105 [25]

The associative property states that we can regroup the terms of an expression and obtain the same result.

We have then:

a + (b + c) = (a + b) + c

The expression that complies with this property is given by:

(-4 + i) + 4i = -4 + (i + 4i)

Answer:

An equation that shows an example of the associative property of addition is:

a. (- 4 + i) + 4i = -4 + (i + 4i)

The ingredients are doubled in the large Totally Turkey Sandwich. On Wednesday, three times as many customers ordered the regula
11111nata11111 [884]

Answer:

45 slices of turkey used

Step-by-step explanation:

In order to figure out this problem we first need to calculate the total amount of sandwiches that were ordered. Since 27 regular sandwiches were ordered and we know that three times as many customers ordered the regular sandwich as the large sandwich. Then we simply divide 27 by 3 to find out how many large sandwiches were ordered.

27 / 3 = 9 large sandwiches.

Now, assuming that each regular sandwich only takes one slice of turkey, we can multiply 9 by 2 since each large sandwich takes double the slices and add that to 27 to calculate the total number of slices used in all of the sandwiches for that day.

(9*2) + 27 = s

18 + 27 = s

45 = s

There were a total of 45 slices of turkey used.

Lee records the height of players on a basketball team, and calculates the mean absolute deviation of the set of data. What does
Luba_88 [7]

The mean absolute deviation can be defined as the average distance between the mean and each of the given data points. It is the absolute value of the deviation.

To find the mean absolute deviation, take the folllowing steps:

1. Find the Mean

2. Find the distance of each value from the mean by Subtracting the mean value from each value

3. Find the mean of the distances

Therefore, the mean absolute standard deviation of the set of data describes the average difference in height between each player and the mean height

ANSWER:

The average difference in height between each player and the mean height
