Explanation

To find the percentage of girls, you need to divide the number of girls (28) by the total number of students (20 boys + 28 girls = 48) and multiply by 100:

(28 ÷ 48) x 100 = 58.3%

So, the percentage of girls in the class is 58.3%.

Explanation

Step 1: Let's denote the two numbers as x and y.
We have two equations:

1. x + y = 28

2. x - y = 4

Step 2: Solve the system of equations.
Adding the two equations eliminates y:
(x + y) + (x - y) = 28 + 4
2x = 32
Step 3: Solve for x.
x = 32 / 2
x = 16
Step 4: Solve for y.
Substitute x into one of the original equations:
16 + y = 28
y = 28 - 16
y = 12
Step 5: Identify the correct pair of numbers.
The numbers are 16 and 12.

Explanation

Look at the pattern:

1 + 2 = 5  

1 square + 2 square = 1 + 4 = 5

2 + 3 = 13  

2 square + 3 square = 4 + 9 = 13

3 + 4 = 25  

3 square + 4 square = 9 + 16 = 25

So the rule is: a + b = a square + b square

Now find 4 + 5  

4 square + 5 square = 16 + 25 = 41
