Step-by-step explanation:

Answer:

x = 1/2 , x = 1/4 , x = 1/3

Step-by-step explanation:

Factor the following equation --> 24x^3 — 26x^2 + 9x — 1 = 0

You will get ----> (2x - 1) (4x - 1) (3x - 1) = 0

Now make all the above expressions = 0 and solve.

2x - 1 = 0                                4x - 1 = 0                                 3x - 1 = 0

    +1    +1                                    +1    +1                                      +1     +1

if 6x=9y find the value of x:y.​

Answers

Answer:

A complete angle is one which measures 360∘360∘.

The three angles

6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘

add up to 360∘360∘, as per the question.

6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘

⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘

⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘

⟹2x+3y+z=90∘⟹2x+3y+z=90∘

This is the required relation.

Answers

Answer:

19

for 1/6 you can get the answer by getting 1/2 chicken = 3/6 then 1/3 tomato soup = 2/6 and you have 1/6 left which will be the answer.

For the number of people, 1/6 is equal to 40 because 240 divided by 6 equals 40
