Answer:
y = 6
x = 2
Step-by-step explanation:
rearrange the first equation in terms of x
x = (y - 2)/2
substiute x in the second equation
y = -5[(y-2)/2] +16
Now simpilify and solve for y
y = (-5y + 10)/2 +16
y = -5/2y + 5 + 16
y + 5/2y = 5 + 16
3.5y = 21
y = 6
Now substitue y in the first equation to solve for x
x = (6 - 2)/2
x = 2

Answer:
4 Cubes
Step-by-step explanation:
A box 4 cm by 6 cm by 8 cm is painted on all six faces.
The volume of the box = L × B × W
V = 4 × 6 × 8 = 192 cm³
The box cut into cubes with the 2 cm sides.
Volume of the 2 cm cube = 2 × 2 × 2 = 8 cm³
The number of cubes from the box = 
= 24 cubes
There would be 4 cubes in the middle would be painted only one side.
Periphery cubes of the box are painted on two or more sides.
