Let Cg = number of girls in Choir club; Cb = number of boys in Choir club

    Rg = number of girls in Robotics club; Rb = number of boys in Robotics club

We are told

Cg = 32

Rg = 19

Cb = Rb*5/7

Cg + Cb = Rg + Rb + 5

Can you take it from here?

1000 cm³ = 1 litre

1 cm³ = 10^-3  litres

8.74×10^-24 cm³ = 10^-3*8.74×10^-24 = 8.74×10^-27 litres

 8.74×10^-27​ litres =  8.74×10^-27​*10⁶ =  8.74×10^-21​ microlitres 

"Two real numbers are chosen at random between 0 and 2. What is the probability that their sum is no more than 1?"

Let p be the initial number of pens.

Number of pens after step

1.    p*5/6 + 4

2. (p*5/6 + 4)*3/4 + 3

3. [(p*5/6 +4)*3/4 + 3]*2/3 + 2 

So [(p*5/6 +4)*3/4 + 3]*2/3 + 2  =  46

Can you take it from here?

Since 1 + 10 + 27 (the coefficients of the x^3, x^2 and x terms respectively) make 38, the root is x = 1.

What about \(\sqrt[12]{4096}=2\) as well?

As follows:
