Answer:
see below
Step-by-step explanation:
2/3y + 15 = 9
Subtract 15 from each side
2/3y + 15-15 = 9-15
2/3y = -6
Multiply each side by 3/2 to isolate y
3/2 * 2/3y = -6 *3/2
y = -9

Good luck :)
Step-by-step explanation:
S=2πrh+2πr ²
subtract 2πr ² from each side
S -2πr ² = 2πrh
divide by 2πr from each side
(S -2πr ² )/ 2πr = h
Answer:
The answer would be 35/12 or 2 and 3/4
Step-by-step explanation:
First we need to convert the fractions, so that they have the same denominator. A common denominator is 12. So, we mulitply 4 by 3 (because 4 X 3 = 12) and we do the same thing for 9. This makes the fraction 27/12. Now we mulitply 2/3 by 4 (because 3 X 4 = 12) and we also multiply 4 by 2 which gives us 8/12. Add 27/12 + 8/12 and you get 35/12 which can be simplified to 2 and 3/4.
