Hello from MrBillDoesMath!
Answer:
x = -1/27
Discussion:
3 x^(1/3) -1 +2 = 0 =>
3 x^(1/3) +1 = 0 => (as -1 + 2 = 1).
3 x^(1/3) + 1 - 1 = 0 - 1 => Add -1 to both sides
3 x^(1/3) = -1 => (divide both sides by 3)
(3/3) x^(1/3) = -1/3 =>
x^(1/3) = -1/3 =>
x = (-1/3) ^3 =>
x = -1/27
Thank you,

Answer:
Bartley has 50 cups of milk
Step-by-step explanation:
5/7 cups of milk so that will be they answer because your droping it and not hearing it
5/7=x/10
Cross multiply
(5)(10)=50
(7)(x)=7x
7x=50
Divide by 7 for both sides
7x/7=50/7
x=50/7 or x=7 1/7
Answer: x=50/7 or x=7 1/7
