Answer:
D)
Step-by-step explanation:
Because
a) 10 = 2(5) = 10
b) 10 = 5 + 5 = 10
c) 10 = 15 -5 = 10
d) 10 = 5 - 5 = 0 the result is not equivalent
Step-by-step explanation:
45% of number = 180
=> 100% of number = 180 * (100/45) = 400.
Hence the number is 400.
Answer:
-2x+2y+3z=0
-2x-y+z=-3
2x+3y+3z=5
---------------
-2x+2y+3z=0
-2x-y+z=-3
---------------- Subtract
3y + 2z = 3 Eqn A
=========================
-2x-y+z=-3
2x+3y+3z=5
---------------- Add
2y + 4z = 2
6y + 4z = 6 Eqn A times 2
------------------------------------ Subtract
-4y = -4
y = 1
-----------------
z = 0
-------------------
x = 1
We know that the formula for the volume of a box is:

Where:
l = length
w = width
h = height
The formula of the surface area of a box is:

Based on the given we know the following:

and

If we factor out the given volume, you can come up with 3 numbers that will satisfy the surface area formula:

Let:
l = 6cm
w = 7cm
h = 13cm
Now let's try this on the surface area formula:





The answer is then:
l = 6cmw = 7cmh = 13cmAny order would be fine.
