She can shake everyone's hand by 9/10 hands in 3 minutes.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Glurpina is a polymorph alien and can grow extra limbs.
She has 3 hands and can shake everyone's hand at the alien conference in 10 minutes.
She can shake everyone's hand by 3 hands in 10 minutes.
She can shake everyone's hand by 1 hands in 10 / 3 minutes.
She can shake everyone's hand by how many extra hands in 3 minutes.
= 3/ 10 x 3
= 9/10
Thus, She can shake everyone's hand by 9/10 hands in 3 minutes.

Answer:
The first graph.
Step-by-step explanation:
Algebra Calculator.
2x + 4 = 12
We're simply just trying to isolate x.
So, we must get x onto it's own side of the equal sign :)
Our first step is to subtract 4 from both sides.
2x + 4 - 4 = 12 - 4
Simplify.
2x = 8
Then, we divide both sides by 2.
2x ÷ 2 = 8 ÷ 2
Simplify.
x = 4
----------
To check your work, simply plug in the value of x into x in the original equation.
In this problem, x = 4, so plug in 4 for x.
2x + 4 = 12
2(4) + 4 = 12
Simplify.
8 + 4 = 12
12 = 12
Therefore, x = 4
