Answer:
Step-by-step explanation:
Since you have an expression for y, it is convenient to use it.
-2x + 8(3x) = -22 . . . . . substitute 3x for y in the second equation
22x = -22 . . . . . simplify
x = -1 . . . . . . . . . .divide by 22
Substituting this value into the expression for y:
y = 3(-1) = -3
The solution is (x, y) = (-1, -3).
A cone always contain a right angle.
To solve for the volume of a cone, we need to get the radius of the cone and its height.
Volume of a cone = π r² h/3
radius is the line from the center of the circle of the cone going to the edge of the circle.
height is the measurement of the cone from its pointy tip going downward.
Assuming the radius of the cone is 3 in. and its height is 6 inches.
Volume of a cone = π * r² * h/3
V = 3.14 * (3in)² * 6in/3
V = 3.14 * 9in² * 2in
V = 56.52 in³
Hank is 9 years old. Explanation - What I did is I made a chart, and the categories were Sam and Hank. Then all I did was add 5 to Sam's age and added 3 to Hank's age. I repeated this until the sum of the ages equaled 24.
