|y-9|=6
y-9=6
y-9=-6
y=15
y=3
So, y=15,3
The given identity tells you ...
.. (sum of numbers) * (sum of squares - product) = (sum of cubes)
Substituting the given information, you have
.. (sum of numbers) * (29 -10) = 133
Then you can divide by (29 -10) to get
.. sum of numbers = 133/19 = 7
The sum of the two numbers is 7.
Answer:
The correct answer is 8
Step-by-step explanation:
It’s 8, because 5- (-3) is like saying 5+ 3, because in math when your dealing with negatives, 2 negitives means the answer is positive and 1 negative means the answer is negative. Hope this helps! :)
The first step would be to add 7 to both sides.
3n-7=30
add 7
3n=37
divide by 3
n=12.33
