Answer:
the girls be 12 and boys be 48 respectively
Step-by-step explanation:
The computation of the number of boys and number of girls is shown below:
Let us assume A be girls
And, b be boys
According to the question
b = 4 × a
b - 8 = 2 × (a + 8)
b - 8 = 2 × a + 16
4 × a -8 = 2 × a + 16
4 × a - 2 × a = 16 + 8
2 × a = 24
a = 12
Now
b = 4 × a
= 4 × 12
= 48
Hence, the girls be 12 and boys be 48 respectively
The equation that you put is correct
Answer: 60
Step-by-step explanation:
Area = ½base × height
600 = ½b × 20
600/20 = ½b
Base = 30 × 2
