Answer: The price of item is $495.

Step-by-step explanation:

Since we have given that

Amount that Sara have = $90

Amount that Rachel have = $405

If they combine their money they will have enough to buy item.

So, Price of item would be

Amount that Sara have + Amount that Rachel have

=90+405\\\\=\$ 495

Hence, the price of item is $495.

Edmund makes a cube using eight small cubes.
anyanavicka [17]

Answer: 184

Step-by-step explanation:

so edmund would have a 2 by 2 cube (try and draw it out if that helps) so

2 x 2 = 4

2 x 3 = 6

2 x 4 = 8

so samuel cubeboid would be

long = 4

wide = 6

hight = 8

8 x 6 x 4 = 192 small cubes

but we are trying to find how much more samuel got

so 192 - 8 = 184

Simplify the expression. 12x^-6 y^10 times 3x^7 y
Vlada [557]

We need to simplify the expression:

12x^{-6}y^{10} \times (3x^{7}y)

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,  

12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)

On simplifying the above expression we get:

36\times x^{(-6+7)}\times y^{(10+1)}

=36 \times x^{1}\times y^{11}

=36 \times x \times y^{11}

=36xy^{11}

So the simplified form of the expression 12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}.

Which values for x and y make the statement (x + 5)(y - 6) = 0 true?
-BARSIC- [3]
<span>                             ||Solving \ for \ x. ||  </span>

(x + 5)(y - 6) = 0 

(x + 5)(y - 6) = 0 :x

&#10;x+5=0&#10; &#10;  |Divide \ both \ sides \ by \ y-6| 

&#10;x=-5&#10; &#10;  |Subtract \ 5 \ from \ both \ sides|

                           ||Solving \ for \ y. || 

&#10;y-6=0&#10; &#10;  |Divide \ both \ sides \ by \ x+5| 
 
&#10;y=6&#10; &#10; 

Solution =\ \textgreater \ x = -5, y = 6
