Number 1 is 32 and the second one is 85
The price before the tip was 8 dollars
<u>Given</u>:
The given equations are
and 
We need to determine the pair of numbers that is a member to the system of equations.
<u>Pair of numbers:</u>
The pair of numbers can be determined by solving the system of equations.
Let us use the substitution method to solve the equations.
Substituting
in the equation
, we have;




Thus, the value of x is 1.
Substituting x = 1 in the equation
, we get;



Thus, the value of y is 7.
Hence, the pair of numbers that is a member of both the equations are (1,7)
The top one is a and the last one is d
Answer: the height would be 15
Step-by-step explanation:
v= pi*radius^2*height
1215pi mm= pi*9^2*height
1215pi mm= pi*81*height
(divide by pi on both sides, which isolates pi on both sides)
1215 mm= 81*height
(divide by 81 on both sides, which would isolate 81 on the right side of the equation)
1215/81= 15= height
