On March 8, 2017, one British pound was worth 1.23 U. S. dollars. (a) On that date, how many dollars was 163.23 pounds worth? Round your answer to the nearest hundredth of a dollar. (b) On that date, how many pounds was 10.79 dollars worth? Round your answer to the nearest hundredth of a pound.

ratio is 2 : 9

the answer is three

13.5 : 3

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
