Phoebe andy and polly share 270 phoebe gets 3 times the amount as andy does who gets twice as much as polly

Polly's money is 30, Andy's is 60, and Phoebe's is 180.

Step-by-step explanation:

Given that

Phoebe andy and polly share 270

Phoebe gets 3 times as andy

And, andy gets twice as much as polly

let us assume the following things

B be Phoebe's money

A be Andy's money

L be Polly's money

Now following equations should be used

B + A + L  = 270  (1)  

B = 3A(2)

A = 2L      (3)          

So,        

B = 3A

= 3 × (2L)

= 6L        

Now put the equation 2 and equation 3 in equation 1

So,

6L + 2L + L = 270

9L = 270

L = 30

A = 2L

= 2(30)

= 60

B = 3A

= 3(60)

= 180

Therefore, Polly's money is 30, Andy's is 60, and Phoebe's is 180.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
