At the carnival, Marsha bought 10 ride tickets and 3 snacks. Each ride ticket costs $1.50 less than a snack. Marsha spent a total of $24.00. Write and solve an equation to find the cost of each snack.

step-by-step explanation:

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

3+3+3+2*2*2+29*12 = 365

step-by-step explanation:

the anwser is x< -17/2
