Answer:
x = -2, y = -3
Step-by-step explanation:
Multiply eqn1 by the LCM of 1 and 6 i.e coefficients of x
We get:
<u> </u><u> </u> 6x - 54y = 150 (eqn1)
<u>6x - 5y = 3</u> (eqn2)
<u> - 49y = 147</u>
y = <u>147</u>
-49
y = -3
Substitute y in eqn2
6x - 5(-3) = 3
6x + 15 = 3
6x = -12
x = -2
Since you're painting the sides of the cube, you will need the equation for the surface area of a cube, which is
![SA = 6s^{2}](https://tex.z-dn.net/?f=SA%20%3D%206s%5E%7B2%7D%20)
, where SA = surface area and s = length of an edge of the cube.
You're told that the edge length, s = 2cm. Plug this into the equation for surface area:
The surface area that will be painted is <span>
24 cm².</span>
The answer is 0.74, or 74 cents
