Given:
The expressions are:



To find:
The value of given expression by using integer tiles.
Solution:
We have,

Here, both number are positive. When we add 6 and 3 positive integer tiles, we get 9 positive integer tiles as shown in the below figure. So,

Similarly,

Here, 6 is positive and -4 is negative. It means we have 6 positive integer tiles and 4 negative integer tiles.
When we cancel the positive and negative integer tiles, we get 2 positive integer tiles as shown in the below figure. So,


Here, 6 is positive and -6 is negative. It means we have 6 positive integer tiles and 6 negative integer tiles.
When we cancel the positive and negative integer tiles, we get 0 integer tiles as shown in the below figure. So,

Therefore,  .

-24.3 feet
-22.55-19.5 is -42.05
-42.05+ 17.75 is -24.3
        
             
        
        
        
(20+2.5)x = cost 
when x equals number of tickets
(20+2.5)24 = 540
        
             
        
        
        
Traffic rules are set by each individual state.
In most states, an intersection where traffic lights are out of order 
is treated as if it were a 4-way STOP.
But you can't depend on this answer.  You MUST determine what 
the law is in the state where you're driving.  And if you drive out of 
state, it may change for you.
