Answer:
There are 10 boys and 6 girls in the class
Step-by-step explanation:
The given parameters are;
The number of boys = The number of girls + 4
The number of students in the class = 16
Let x represent the number of girls in the class and let y represent the number of boys in the class
Therefore;
y = x + 4...(1)
x + y = 16...(2)
Making y the subject of equation (2) gives;
y = 16 - x
Equating the values of y from equation (1) and equation (2) gives;
x + 4 = 16 - x
Which gives;
2·x = 16 - 4 = 12
x = 12/2 = 6
x = 6
The number of girls = x = 6
From equation (1), we have;
y = x + 4 = 6 + 4 = 10
y = 10
The number of boys = y = 10.
Answer:
4a^2+2ab+362 = 2(2a^2+ab+181)
-a^2-3ab+62 = -(3ab+a^2-62)
Step-by-step explanation: For question #1, factor 2 out of 4a^2+2ab+362.
For question #2, factor -1 out of -a^2-3ab+62.
Hope this helps you out.

Answer:
fraction is 44/100
decimal form is 0.44
percentage is 44%

The solution to the system of equations is (-3, -5) because the point satisfies both equations
<h3>What is a
linear function?</h3>
A linear function is in the form:
y = mx + b
Where m is the slope (rate of change) and b is the y intercept
Line A:
y = x − 2 (1)
Line B:
y = 3x + 4 (2)
Solving both equations simultaneously gives:
x = -3, y = -5
The solution to the system of equations is (-3, -5) because the point satisfies both equations
