Answer:
The ratio of the contribution x:y:z is 6:8:11
Step-by-step explanation:
Firstly, we need to know the amount in which Z got
That will be 250,000-x-y
= 250,000- 60,000 - 110,000 = 80,000
So the ratio of the contribution in x:y:z will be;
60,000:110,000:80,000
= 6:11:8
Eloise made these steps well:
Square root of negative 2x plus 1 - 3 = x
Square root of negative 2x plus 1 - 3 + 3 = x + 3
The error comes in the next step:
Square root of negative 2x plus 1 = x + 3
Square root of negative 2x plus 1 -1 = x + 3 - 1
Square root of negative 2x = x + 2
the number one is inside the root, therefore they can not be subtracted.
answer
error in the step:
Square root of negative 2x = x + 2
that's the answer
Step-by-step explanation:

Answer:
y = 17/2
Step-by-step explanation:
7y − 4 = 9y + 13 − 4y
Simplify both sides of the equation.
7y - 4 = 5y + 13
Subtract 5y from both sides.
2y - 4 = 13
Add 4 to both sides.
2y = 17
Divide both sides by 2.
y = 17/2
I hope this helps! Feel free to ask any questions!
X-4/3 = 3x-4/7
First add 4/3 to each side -->x = 3x + 16/21
Then Subract 3x from each side -->-2x = 16/21
Then divide each side by -2 --->x = -3.81
