Answer:

x = 2

y = 1

Step-by-step explanation:

3x - y = 5..............(1)× 1

2x + y = 5...….......(2)× 1

3x - y = 5..............(3)

2x + y = 5.............(4)

Cancel y

3x + 2x = 5 + 5

5x = 10

Divide both sides by 5

x = 2

Substitute for the value of y

3x - y = 5

3(2) - y = 5

6 - y = 5

6 - 5 = y

1 = y

y = 1

xxMikexx [17]

Formula for volume of a sphere: V = (4 / 3)(pi)(r^3)

Formula for circumference: C = (pi)(2r)

Solving for radius using circumference formula:

12 = (pi)(2r)

2r = 12 / pi

r = 12 / 2pi

Solving for volume:

V = (4 / 3)(pi)((12 / (2pi))^3)

Plug into calculator

V = 29.18 in^3

Hope this helps!! :)

nika2105 [10]

It is given in the question that your computer monitor has a width of 14.98 inches and a height of 11.24 inches.

And we have to find the area of the monitor display in square meters.

And the formula of area is width times height .

SO to find the area, we have to multiply the given width and height.That is

Area= 14.98*11.24 =168.3752 square inches

And now we need to convert square inches to square meters and for that we have to multiply the given answer by 0.00064516. That is

= 168.3752*0.00064516=0.1086 m^2
