Answer:


Step-by-step explanation:
← Equation 1

By simplifying the above equation we get,
(Simplifying the brackets)
(By subtracting
from
) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,

Equation 2 multiplied by 3 will give,

Add those together,
(After simplifying
values)
Therefor 
By substituting
to Equation 1 we get,


Therefor we can say,


Answer: The slope is -6/5
Step-by-step explanation:
Answer:
240/r = h
Step-by-step explanation:
480π = πr2h Write out the equation
480 = r2h Cancel out π on both sides
240 = rh Divide by 2 on both sides
240/r = h Divide by r to isolate h and get your answer
2n + 20 = -2
20 + 2 = -2n
22 = -2n
22/2 = n
11 = n
