Step-by-step explanation:

By the geometric mean theorem,

12/9 = 9/x

-> x=81/12 = 27/4

Then by the Pythagorean theorem,

y=sqrt(9^2 + (27/4)^2), which you can probably calculate yourself.

Hilda has $210 worth of $10 and $12 stock shares. The number of $10 shares is five more than twice the number of $12 shares. How

klasskru [66]

Let's first define variables.
y: number of shares of $ 10
x: number of shares of $ 12
We write the system of equations:
10x + 12y = 210
y = 2x + 5
Solving the system:
x = 75/17
y = 235/17
Answer:
she has:
75/17 shares of $ 12
235/17 shares of $ 10
