Answer:
x = 2.4 or x = 0.3
Step-by-step explanation:
3x² - 8x + 2 = 0
Quadratic formula
x = {-b ±√b² - 4ac} / 2a
a = 3
b = -8
c = 2
x = {-b ±√b² - 4ac} / 2a
= {-(-8) ±√(-8)² - 4*3*2} / 2*3
= (8 ± √64 - 24) / 6
= (8 ± √40) / 6
= (8 ± 2√10) / 6
= 8/6 ± 2√10/6
= 4/3 ± √10 / 6
x = 4/3 + √10 / 6 or 4/3 - √10 / 6
x = 2.4 or x = 0.3

Answer: D
Step-by-step explanation:Lets label hot dogs as 'h' and soft drinks as 's'
6h + 4s = 13 (Equation 1)
3h + 4s = 8.50 (Equation 2)
We can solve by process of elimination.
Subtract equation 1 from equation 2.
We get:
3h = 4.5
h = 1.5
So that means that the hot dog costs $1.50 which is answer choice D.
