<span>The total number of students in the class is 9 + 7 = 16
The probability first person is a girl is 9/16
The probability second person is a girl is 8/15
The probability third person is a girl is 7/14
The probability that three girls are the first to enter is 9/16 * 8/15 * 7/14 = 504/3360 = 0.15. Option A.</span>
We can write a system of equations.
x + y = 77
y = x + 5
Plug in x + 5 into the first equation:
x + y = 77
x + (x + 5) = 77
So this is our answer.

Answer:
Step-by-step explanation:
area of circle = πr² = 25π ft²
area of sector = 25π × 221°/360° ≅ 48.21 ft²
<2 and <3 are supplementary angles...therefore they must equal 180°
since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°
180 - 125 = 55° < answer
hope this helps :)
