A group of students takes a test and the average score is 72. One more student takes the test and receives a score of 88 increas
Stells [14]

Answer:

3 student.

Step-by-step explanation:

From the first statement:

Let the total score be T

Let the total number of student be x

The average of the score = 72

Average = Tota score / number of student

72 = T/x

Cross multiply

T = 72x ..... (1)

Second statement:

One more student took the test and the average becomes 76 with the student having a score of 88.

Therefore,

Overall score = T + 88

Total student = x + 1

Average = 76

Average = overall score / total number of student

76 = (T + 88) /(x + 1)

Cross multiply

76(x + 1) = T + 88

Clear bracket

76x + 76 = T + 88

From equation 1

T = 72x

76x + 76 = 72x + 88

Collect like terms

76x – 72x = 88 – 76

4x = 12

Divide both side by the coefficient of x i.e 4

x = 12/4

x = 3

Therefore, the initial number of the student were 3.

Answer:

1.5

Step-by-step explanation:

The constant of proportionality is the slope

m= (y2-y1)/(x2-x1)

Pick any two points

m = (12-6)/(8-4)

   = 6/4

   = 3/2

   = 1.5

Solve for x<br><br> (1.) 5/10x-9=8<br><br> (2.) 3/4x-3=1+5/12x
Yakvenalex [24]

Answer:

1). x=\frac{5}{170}

2). x=\frac{1}{12}

Step-by-step explanation:

(1.)  \frac{5}{10x}-9=8

adding 9 on both sides we get

\frac{5}{10x}=9+8

\frac{5}{10x}=17

5=17 \times 10x

x=\frac{5}{170}

(2.)  \frac{3}{4x}-3=1+\frac{5}{12x}

\frac{3}{4x}-\frac{5}{12x}=1+3

\frac{9-5}{12x}=4

\frac{4}{12x}=4

12x=1

x=\frac{1}{12}
