Answer: Using the information of the conditional relative frequency table, 123 students in the survey said that math was their favorite subject.
Solution:
1. The survey was given to 120 male students.
Acconding with the table, the proportion of male students with Math as favorite subject is 0.35. The quantity of male students with Math as favorite subject would be:
0.35(120)=42 male students
2. The survey was given to 180 female students.
Acconding with the table, the proportion of female students with Math as favorite subject is 0.45. The quantity of female students with Math as favorite subject would be:
0.45(180)=81 female students
Then the total of students in the survey said that math was their favorite subject would be:
42 male students + 81 female students = 123 students
The given equation solved for A is A = (T + 5)/ B
<h3>Solving linear equation</h3>
From the question, we are to solve the given equation for A
To solve the equation for A, we will simply make A the subject of the equation
The given equation is
T = AB - 5
Solving for A
T = AB - 5
Add 5 to both sides of the equation
T + 5 = AB - 5 + 5
T + 5 = AB
Divide both sides of the equation by B
That is,
(T + 5)/B = AB/B
(T + 5)/B = A
∴ A = (T + 5)/ B
Hence, the given equation solved for A is A = (T + 5)/ B

Answer:
1. <u>14x</u> and <u>7</u> and <u>9x</u> and <u>3</u>
2. <u>0x</u>
3. <u>4</u>
Step-by-step explanation:
Step 1: Distribute
First, multiply 7 by 2x and 1 to get 14x and 7. Then multiply -3 by 3x and 1 to get -9x and -1
Step 2: Combine like variable terms
Combine 14x, -5x, and -9x, to get 0x.
Step 3: Combine like constant terms
Combine 7 and -3, to get 4.
