namely what's 240⅛ - 215⅝.
firstly, let's convert the mixed fractions to improper, and then divide.
I think the answer is 7.66666666667 because 1150 ÷ 150 = 7.66666666667
Your answer is x = 1/3 or x = -1
To solve I would start by expanding the bracket and then collecting like-terms, and then re-factoring:
(3x - 1)² + 12x - 4 = 0
9x² - 6x + 1 + 12x - 4 = 0
9x² + 6x - 3 = 0
3(3x² + 2x - 1) = 0
From here you can factorise the bracket even further:
3(3x - 1)(x + 1) = 0
Then divide by 3:
(3x - 1)(x + 1) = 0
3x - 1 = 0
x = 1/3
x + 1 = 0
x = -1
I hope this helps! Let me know if you have any questions :)
Addition is the inverse of subtraction and multiplication is the inverse of division.
Ex: 1+1 = 2, 2-2 = 0
Answer:
4:9
Step-by-step explanation:
12 red apples and 27 apples in total so it would be 12:27. Just divided it by 3
I think that's what the question is asking...
