-2y = 48 + 6x
-6x - 2y = 48 ——(1)
-6x + 9y = -84
-6x = -84 -9y ——(2)
Substitute (2) into (1):
(-84 -9y) -2y = 48
-84 -9y -2y = 48
-84 -11y = 48
-11y = 48 + 84
-11y = 132
y = - 12
Substitute y = -12 into (1):
-6x -2(-12) = 48
-6x + 24 = 48
-6x = 48 -24
-6x = 24
X = -4
ANS : y= -12, x= -4
Answer:
Fiona has 6 quarters
Step-by-step explanation:
If Fiona were to have 1 quarter and 1+6 dimes she would have 8 coins
If she were to have 2 quarters and 2+6 dimes she would have 10 coins
If she were to have 3 quarters and 3+6 dimes she would have 12 coins
If she were to have 4 quarters and 4+6 dimes she would have 14 coins
If she were to have 5 quarters and 5+6 dimes she would have 16 coins
If she were to have 6 quarters and 6+6 dimes she would have 18 coins
Therefore, she has to have 6 quarters in order to have 6 more dimes and a total of 18 coins

Answer:
The surface area of the drum is 3317.5218 square inches.
Step-by-step explanation:
Drum's have a cylindrical form, therefore in order to calculate its surface area we need to apply the correct formula, as shown below:
Where the first term of the sum is the area of the lid and bottom of the drum and the second term is the area of the walls of the drum, r is the radius and h is the height. Applying the data from the problem, we have:
The surface area of the drum is 3317.5218 square inches.
