Use the elimination method to solve the system of equations. Choose the
Yakvenalex [24]

Answer:

(2, 7) is the correct ordered pair.

Step-by-step explanation:

5x + 3y = 31

2x + 3y = 25   Subtract to eliminate the y variable:

3x = 6

x = 6/3

x = 2.

Substitute x = 2 in the first equation:

5*2 + 3y = 31

3y = 31-10 = 21

y = 21/3

y = 7.

Check the result by substituting for x and y in the second equation:

2(2) + 3(7) = 25

4 + 21 = 25

25 = 25.

Please help me with this question!
Rasek [7]

Answer:

87 packages

Step-by-step explanation:

First we need to find the volume of the cone-shaped vase.

The volume of a cone is given by:

V_cone = (1/3) * pi * radius^2 * height

With a radius of 9 cm and a height of 28 cm, we have:

V_cone = (1/3) * pi * 9^2 * 28 = 2375.044 cm3

Each package of sand is a cube with side length of 3 cm, so its volume is:

V_cube = 3^3 = 27 cm3

Now, to know how many packages the artist can use without making the vase overflow, we just need to divide the volume of the cone by the volume of the cube:

V_cone / V_cube = 2375.044 / 27 = 87.9646 packages

So we can use 87 packages (if we use 88 cubes, the vase would overflow)
