Consider each of the following relationships. Which school shows the greatest rate of change between male and female students? ​
denis-greek [22]

Answer:

The greatest rate of change is for <u>school A</u> as it has the greatest ratio of 2.5

Step-by-step explanation:

School A:

Ratio of male to female students, m_A=5:2=\frac{5}{2}=2.5

School B:

Male students are related to female students by equation:

y=2x

Where, x means number of female students and y means number of male students.

Therefore, the ratio of male to female students is, m_B=\frac{y}{x}=2

School C:

Ratio of male to female students is, m_C=\frac{\textrm{Number of male students}}{\textrm{Number of female students}}=\frac{200}{120}=1.67

Now, rate of change of male to female students is directly proportional to the ratio of the two.

Hence, the greater the ratio, the greater the rate of change.

So, the greatest rate of change is for school A as it has the greatest ratio of 2.5

PLS ANSWER I WILL GIVE YOU BRAINLIST AND A THANK YOU!!
Arte-miy333 [17]

Answer:

x=45

Step-by-step explanation:

2x+45+x=180

Combine 2x and x to get 3x.

3x+45=180

Subtract 45 from both sides.

3x=180−45

Subtract 45 from 180 to get 135.

3x=135

Divide both sides by 3.

x=135/3

Divide 135 by 3

x=45
