Answer:
d. 4.5 
Step-by-step explanation:
10x-5=16x+22
     -22      -22
10x-27=16x
-10x      -10x
-27=6x
x=4.5
 
        
                    
             
        
        
        
In mathematics multiplying decimals is just like multiplying a whole number and ignoring the decimals., then just put the decimals in the answer – it is how many decimals does the two numbers combined.
First step:
Line the numbers on the right and do not a line the decimal points
      26.2
×  16.43
Second Step:
Multiply the numbers starting on the right, just like multiplying a whole number and ignore the decimals.
       26.2
<span> ×  16.43</span>
         786
     1048
   1572
<span>+ 262   </span>
   430466
Third step: add the products
        26.2
<span> ×  16.43</span>
         786
     1048
   1572
<span>+ 262   </span>
   430.466 is the mathematician’s answer.
 
        
             
        
        
        
Answer:  The corrected statement is A - B = -B + A. 
Step-by-step explanation:  Given that the subtraction of a matrix B may be considered as the addition of the matrix (-1)B.
We are given to check whether the commutative law of addition permit us to state that A - B = B - A.
If not, We are to correct the statement.
If the subtraction A - B is considered a the addition A + (-B), then the commutative law should be stated as follows :
A + (-B) = (-B) + A.
That is, A - B = -B + A.
Thus, the corrected statement is A - B = -B + A, not B - A.
 
        
             
        
        
        
You would find the sign if the signs are not the same if you are dividing or multiplying its negitve if its the same its positive
        
             
        
        
        
Putting the two numbers together in fraction form of a ratio, we have 76/19. We know that something multiplied by 19 will equal to 76. 
When we try to multiply 4 and 19 together, we have our nice answer 76. We then replace out values in the original ratio, in which we get the final answer of 4:1, 4/1, or 4 to 1.
