Answer:
The first option: -5/4x + 1/6. 
Step-by-step explanation:
(3/4x - 2/3) - (-5/6 + 2x)
= (3/4x - 2/3) + 5/6 - 2x
= 3/4x - 2x - 2/3 + 5/6
= 3/4x - 8/4x - 4/6 + 5/6
= -5/4x + 1/6
So, the first option: -5/4x + 1/6. 
Hope this helps!

toppings
Step-by-step explanation:Total cost of cheese pizza:  
$
10.75
Any additional topping adds:  
+
$
1.25
So a cheese pizza with  
1
additional topping is:
$
10.75
+
$
1.25
=
$
12.00
A cheese pizza with  
2
additional toppings is:
$
10.75
+
$
1.25
+
$
1.25
=

A cheese pizza with  
3
additional toppings is:

14.50
If you pay attention to the pattern you can see that, for any number of toppings, say  
x
toppings, the price is going to be:
$
10.25
+
x

$
1.25
We are told the final cost is  
$
17.00
. That is
$
10.25

$
1.25
=
$
17.00
Subtract  
$
10.25
from both sides
$
10.25
−

The answer should be 6f. You multiply the 3 and the 2 and then put the f at the end (:
 
        
                    
             
        
        
        
Answer:
440
Explanation:
If 50% of the total gum balls are red which is 220, then the other 50% is 220.
        
                    
             
        
        
        
You can express the edge lengths in terms of "cubes" or you divide the total volume by the volume of a cube. It works either way.
Edge lengths are
.. 80 cubes by 8 cutes by 13 cubes
so total volume is
.. (80 * 8 * 13) = 8320 cubes
In cubic inches, the volume is
.. (20 in)*(2 in)*(3 1/4 in) = 130 in^3.
The volume of a 1/4-in cube is (1/4 in)^3 = 1/64 in^3.
Then the number of cubes that will fit in the prism is
.. (130 in^3)/(1/64 in^3) = 8320 . . . . cubes
8320 cubes are needed to fill the rectangular prism.
