solve for x.
x+9y=18
Add -9y to both sides.
x+9y+−9y=18+−9y
x=−9y+18
solve for y.
x+9y=18
Add -x to both sides.
x+9y+−x=18+−x
9y=−x+18
Divide both sides by 9.
9y/9=−x+18/9
y=−1/9x+2
Adding a negative is the same as subtracting, so here we have 5/8-5/6. Let's find our least common denominator to use as our common denominator for both fractions. That would be 24. So, we multiply 5/8 by 3/3 because to get an equivalent fraction, you multiply by a version of 1- then you multiply 5/6 by 4/4. So, you get 15/24-20/24 equals -5/24. Hope this helps!
Answer:
3
Step-by-step explanation:
Volume of a cone
V = pi x r^2 x h/3
So plug in the values we have
30pi = pi x r^2 x 10/3
30 = r^2 10/3
9 = r^2
3 = r
The only things you can factor out of here is a 3 so you are left with:
3(y-6)
Hope that helps.
