elena-s [515]

The equation can be modeled as

X + X + (X+4) = 61

X is used for all because they are all the same number and can be given the same variable

The third is given plus four so we can use a common variable

3x + 4 = 61

3x = 57 (subtracted four)

x = 19 (divided by three)

Solving for third side so x + 4

The third side is 23 inches

hammer [34]

Answer:

We can expect 8255 numbers of students are liberal arts majors.

Step-by-step explanation:

Given:

Total Number of students in the college = 8943

Now According to Mr. Jones Survey;

60 out of 65 students are liberal arts majors.

We need to find the number of students who are liberal arts majors out of total number of students in college.

Solution:

First we will find the Percentage number of students who are liberal arts majors according to survey.

Percentage number of students who are liberal arts majors can be calculated by dividing 60 from 65 then multiplying by 100.

framing above quote in equation form we get;

Percentage number of students who are liberal arts majors = \frac{60}{65}\times 100 = 92.31\%

Now we will find the Total number of students who are liberal arts major.

Total number of students who are liberal arts major can be calculated by Multiplying Percentage number of students who are liberal arts majors with total number of students in the college and then dividing by 100.

framing above quote in equation form we get;

Total number of students who are liberal arts major = \frac{92.31}{100}\times 8493 \approx8255.28

Since number of students cannot be in point, so we will round the value.

Hence We can expect 8255 numbers of students are liberal arts majors.
