Let x = the numbers of girls
thus
the numbers of boys = 2x
x + 2x = 27
3x = 27
x = 9
2x = 2 . 9 =18
girls = 9 & boys = 18

Answer: 150 pounds
Step-by-step explanation:
Let the the astronaut weight on Earth be represented by x.
Based on the information given in the question, thus can be formed into an equation as:
16.5% of x = 24.75
16.5% × x = 24.75
16.5/100 × x = 24.75
0.165x = 24.75
x = 24.75/0.165
x = 150 pounds
The astronaut weigh 150 pounds on Earth.
