Answer:
-0.75
Step-by-step explanation:
There are 30 students in class
<em><u>Solution:</u></em>
Let "x" be the total number of students in class
Given that,
The number of boys represents 54% of the class
Therefore,
Number of boys = 54 % of total number of students
Number of boys = 54 % of x
![\text{Number of boys } = \frac{54}{100} \times x\\\\\text{Number of boys } = 0.54x](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20boys%20%7D%20%3D%20%5Cfrac%7B54%7D%7B100%7D%20%5Ctimes%20x%5C%5C%5C%5C%5Ctext%7BNumber%20of%20boys%20%7D%20%3D%200.54x)
Given that, There are 14 girls in a class
Therefore,
Number of girls = 14
Thus we get,
Number of boys + number of girls = total number of students
0.54x + 14 =x
x - 0.54x = 14
0.46x = 14
Divide both sides by 0.46
![x = 30.43 \approx 30](https://tex.z-dn.net/?f=x%20%3D%2030.43%20%5Capprox%2030)
Thus there are 30 students in class
The Value of X is 10.

Here is an explanation for the answer.
Answer:
y-2= - 1/11 (x-3)
Step-by-step explanation:
The slope is m=y2-y1/x2-x1=3-2/-8-3=1/-11=-1/11
Equation of a line is
y-y1=m(x-x1)
y-2= - 1/11 (x-3)
