The weight of galss cube with side 5 cm is 300 grams
<em><u>Solution:</u></em>
A glass cube is of side length 5 cm
Let us first find the volume of glass cube
<em><u>The volume of cube is given as:</u></em>

Thus volume of cube is 125 
Given that, 

So, weight of 125 cubic centimeter of glass cube is found by multiplying weight of 1 cubic centimeter of glass cube by 125


Thus weight of galss cube with side 5 cm is 300 grams
 
        
                    
             
        
        
        
The sum of the left side of these two equations is equal to the same of the right side is these two equations 
4x+8y + (-4x+2y) = 20 + 30
10y =50 ( x is eliminated)
y=5
Take this into the second equation 
-4x +2y = 30
-4x + 2*5 = 30
x=-5
So x=-5
 y=5
        
             
        
        
        
Answer:

Explanation:
The complete question is:
<em>Between the time iko woke up and lunchtime, the temperature rose by 11º. Then by the time he went to bed, the temperature dropped by 14º.</em>
<em />
<em>Write an addition expression for the temperature relative to when iko woke up. </em>
<em />
<h2>Solution</h2>
It is said that between the time Iko woke up and lunchtime, the temperature rose by 11 degrees. A rise means the temperature increased and you must add 11º.
Then, relative to when Iko woke up the temperature is:
Then, by the time Iko went to bed, the temperature dropped by 14º. A drop means that the change is negative. This means that you must add a negative number, and the additive expression is:
If you want the overall change in temperature you do the operation:
- 11 + (-14) =  11 - 14 = - 3. A net decrease of 3º. 
But the answer to this question is the additive expression:

1 foot is 12 inches
Thus 2 feet is 24 inches
Substitute values into equation:
volume = 24 x 24 x 24
volume = 13824
Your answer is option D

Answer:
A. 
Step-by-step explanation:
This is a great question! The first thing we want to do here is to take the constant out of the expression, in this case 5. Doing so we would receive the following expression -

We can then apply the power rule "  ", where a = exponent ( in this case 4 ),
 ", where a = exponent ( in this case 4 ),

From now onward just simplify the expression as one would normally, and afterward add a constant ( C ) to the solution -
 - Add the exponents,
 - Add the exponents,
 - 5 & 5 cancel each other out,
 - 5 & 5 cancel each other out,
 - And now adding the constant we see that our solution is option a!
 - And now adding the constant we see that our solution is option a!
