The answer is the last one. The main goal is to get the initial velocity alone, and by solving that treat it like your solving an equation. I showed the process of how I got the answer attached. But if you want me to explain it, I am glad to do it.

First, write an equation to express what you know.
g = number of girls
b = number of boys
b * 2.52 + g * x = 2.88(b+g)
Solve for x, first substitute known values for g and b
12 * 2.52 + 18 * x = 2.88(12+18)
Add and multiply what you already know
30.24 + 18x = 86.4
Subtract 30.24 from both sides
18x = 56.16
Divide both sides by 18
x = 3.12
Therefore the GPA of the girls is 3.12</span>
Answer:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°
Answer:
82^o
Step-by-step explanation:
74 + 24 = 98
180 - 98 = 82^o
Hope it helps!
