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.

Step-by-step explanation:
Explanation:
Substitute
tan
(
y
x
)
for
θ
tan
(
y
x
)
=
π
3
Obtain
y
x
on the left by using the inverse tangent on both sides:
tan

Multiply both sides by x:

That would be
3x^2 + 4x - 60 - (3x^2 - x + 200)
= 4x - 60 + x - 200
= 5x - 260 Answer
C + t = 75......c = 75 - t
6c + 3t = 312
6(75 - t) + 3t = 312
450 - 6t + 3t = 312
-6t + 3t = 312 - 450
-3t = - 138
t = -138/-3
t = 46 <=== 46 cups of tea were sold
c = 75 - t
c = 75 - 46
c = 29 <=== 29 cups of coffee
