-4y - x - (3y - 9x)...distribute the - thru the parenthesis
-4y - x - 3y + 9x....now combine like terms
8x - 7y <== or -7y + 8x
Answer:
t=4
Step-by-step explanation:
solve for t by deciding both sides by k.
then do 144/36 to get t.
Step-by-step explanation:
The equation is given by :
63.25=800r+3.50
Here,
63.25 is the electric company charges
3.5 is an administrative fee
800 is charge per kilowatt hours
r is rate per kilowatt hour
In this proble, we need to tell that what does r represents. Hence, r shows kilowatt per hour.
We can solve it as follows :
63.25-3.5=800r+3.50-3.50 (Subtracting 3.50 to the both sides)
59.75=800r

9/8
Explanation: a perpendicular slope is the opposite of what the normal slope was before
