There are 33 cans altogether.
4 shelves • 8 cans + 1
4 • 8 + 1 = 33
Hope this helps!
Answer:
x = 1
y = -4
Step-by-step explanation:
You can use 2 methods to solve this, substitution or elimination.
Elimination:
You want to try and get rid of one variable in the pair of equations.
We add them together since y and -y cancel each other out when added.
Now, we have a much simpler equation.
4x - y = 8
+ 6x + y = 2
------------------
10x = 10
x = 1
Now, you can just plug it back in to one of the equations to get y.
(4 x 1) - y = 8
4 - y = 8
y = -4
Substitution:
You can also try and change the equation so that there is only one variable by setting the other equation equal to a variable.
This one is easier to do:
6x + y = 2
y = -6x + 2
Now, plug it into the first equation replacing y, since they are equal, and solve:
4x - y = 8
4x - (-6x + 2) = 8
4x + 6x - 2 = 8
10x = 10
x = 1
Now, you can just plug it back in to one of the equations to get y.
6x + y = 2
(6 x 1) + y = 2
6 + y = 2
y = -4

Answer:
B. 
Step-by-step explanation:
Given,
The number of smaller cubes = 
So, the number of cubes that have no coloured faces. = 
,
Note : If a cube painted outside having side n is split into n³ cubes, then the volume volume that is not painted = (n-2)³
Thus, the remaining cubes that have been painted red on at least one of their faces
= Total cubes - cubes with no painted face
Hence, OPTION B is correct.

Answer:
33
Step-by-step explanation:
46/22=46+23/x
46x=22 times 69
46x=1518
x=33
