8% of x = $18.80
x = 18.80/8%
x = 18.80/0.08
x = $235
        
             
        
        
        
Answer:
-51 (no options are matching)
Step-by-step explanation:
Given: (–2)2 + (–42) + (18 – 23). 
we know, 2*2 = 4, and in integer multiplication if any negative integer is multiplied with positive integer, then the result will have a negative sign.
= -4 + (-42) + (18 – 23) 
Here, we have open the brackets, and written the respective signs with the integers,
= - 4 - 42 - 5
now, we will perform the integer addition. Adding all the positives together & he negative numbers together
= -51
PS: It happens to be that none of the given options match with the correct answer. But, i have solved taking the expression, i hope it helps
 
        
                    
             
        
        
        
Answer:
3x - (15 x 3) = 90 
or 
3x - 45 = 90
Explanation:
there are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45 
Therefore the first part is 3x - 45
We also know that in the end we have 90 left.
So our final equation is:
3x - 45 = 90
 
        
             
        
        
        
Answer:
The answer is 188 
Step-by-step explanation:
because cm is 8 and cm has the exponent of 2 so that will equal 64 and 64 plus the area is 188  
 
        
             
        
        
        
D the terms are three times larger because 5 x 3 = 15
