The 650 students at Sequoyah High School read a total of 18,996 pages during one month of school. What is the average number of
Elena L [17]
This is the concept of statistics, given that there are 650 students and all of them read a total of 18,996 pages. We are required to get the average number of pages that they all read;
Average, otherwise known as the mean is the calculated 'central' value of a set of numbers;
The formula for mean is given by;
mean=(sum)/(count)
in our case:
sum=18,996
count=650
thus;
mean=18996/650
=29.23
Here we can conclude that the average number of pages read by each student in the High School was 29.23

Isabella spent $49 for 7 bracelets. Each bracelet cost the same amount.
n200080 [17]
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.

Equation: number of bracelets bought × cost of each bracelet = total cost

Number of bracelets bought: 7
Total Cost: 49

Using this information, we can fill in the equation and solve for x.

7x = 49

To isolate x, divide both sides by 7.

x = 7

Since x equals 7, we now know that each bracelet cost $7.

Simplify the expression.<br> 55−4⋅5+12
alexandr1967 [171]

Answer:

62.5.

Step-by-step explanation:

Given:

The expression to simplify is given as:

55 - 4.5 +12

We have to use PEMDAS method in order to simplify this.

P stands for parenthesis, E for exponents, M/D stands for Multiplication or Division and A/S stands for Addition or Subtraction.

P has the highest priority followed by E followed by M or D which ever comes first followed by A or S which ever comes first.

Here, the first operation we encounter is subtraction S.

First, we will subtract 4.5 from 55. So, 55 - 4.5 = 50.5

Next operation is addition A.

Now, we will add the result to 12. So, 50.5 + 12 = 62.5

Therefore, the answer is 62.5.
