A computer and printer cost total of $927 the cost of the computer is two times the cost of the planet find the cost of each ite

swat32

The cost of the printer is $309 and cost of the computer is $618.

Step-by-step explanation:

Let x denote the cost of computer

Let y denote the cost of printer

Total cost of printer and computer OR

x + y = $927

To find the cost of x and y,

Cost of computer = 2 x cost of the planet

x = 2y

x+y = 927

2y+y = 927

3y = 927

y = 309

x = 2y

x = 2(309)

x = 618

Therefore, the cost of the printer is $309 and cost of the computer is $618.

Shay is putting a square canvas painting in for her new room, and the area of the canvas painting is 196 cm².

Alika [10]

Answer:

The total distance around the canvas painting is 60 cm.

Step-by-step explanation:

The total distance around the canvas painting is 60 cm, we know this because, to find the perimeter of a square you add the length of all 4 sides together. To find the length of 1 side we take the square root of the area which is 196 cm², this equals 14 cm. To find the perimeter we add all 4 sides together, so 14+14+14+14=60 cm.
