Answer: 
Step-by-step explanation:
We have the equation 
where P represents the payment and w represents the amount of water used.
To calculate the monthly payment that corresponds to 12 units of water you must do 
in the main equation and solve for the variable P.
Answer:
49π and 153.86 when multiplyed by 3.14.
Step-by-step explanation:
Hi!
The formula for finding the area of a circle is πr².
In that case, all we have to do is substitute 7 inches for our r.
7² × π
= 49π
If you want that solved out, we can substitute a rational number for π (3.14)
49 × 3.14 = 153.86
Thus, the area of the circle is 
, 153.86 roughly.
Hope this helps!
3/4+5/6 divided by 2/3 is 8/4 or 2
Do 5/6 divided by 2/3 first to get 5/4
then use 5/4 to +3/4 and the answer is 8/4 or 2
Answer:
{-12,0}
Step-by-step explanation:
first to solve this can collect like terms and add
X² +12x=0
and solve it by factorization method
X² +12x=0
x(x+12)=0
it means x multiplied by x = X² then x multiplied by 12 = 12x
so this means x or (x+12) equals to zero
x=0 and (x+12)=0
x+12=0
x=-12
so the solution set is {-12,0}
but can also be done by formula method
