Answer:
x=0.y=3
Step-by-step explanation:
5x-y=-3
y=5x+3
sub y=5x+3 into 6x+y=3,
6x+5x+3=3
11x=0
x=0
6(0)+y=3
y=3
Answer:

Step-by-step explanation:
Let h be the cylinders height and r the radius.
-The volume of a cylinder is calculated as:

-Since the cone is within the cylinder, it has the same radius as the cylinder.
-Let
be the height of the cone.
-The area of a cone is calculated as;

The volume of the solid section of the cylinder is calculated by subtracting the cone's volume from the cylinders:

Hence, the approximate area of the solid portion is 
Answer:
147,590
Step-by-step explanation:
b/c the 90's are in the tens and 5 or more add one more, so since it's less than five, you round down. So the answer would be 147,590
107.2×.26= 27.87 gallons
107.2 liters, .26 gallons per liter
Set it up as a propotion and cross multiply. 10/23=15/x answer is 34.5
