Answer: 1.76
1.54
Step-by-step explanation:
we have to divide 800 by 453.592, and the result is 1.763699... rounding it: 1.76
now we do the same for 700 :
700 divided by 453.592 is 1.5432... so rounding it down: 1.54
 
        
             
        
        
        
Well since two solid numbers cant make 7 I would do 3.5 x 7
        
                    
             
        
        
        
A=number of seats in section A
B=number of seats in section B
C=number of seats in section C
We can suggest this system of equations:
A+B+C=55,000
A=B+C                                      ⇒A-B-C=0
28A+16B+12C=1,158,000
We solve this system of equations by Gauss Method.
1             1              1               55,000
1            -1            -1                         0
28         16           12          1,158,000  
1             1              1               55,000
0            -2             -2             -55,000                                    (R₂-R₁)
0           12             16           382,000                                    (28R₁-R₂)  
1            1                1              55,000
0           -2              -2             -55,000 
0            0                4               52,000                                     (6R₂+R₃) 
Therefore:
4C=52,000
C=52,000/4
C=13,000
-2B-2(13,000)=-55,000
-2B-26,000=-55,000
-2B=-55,000+26,000
-2B=-29,000
B=-29,000 / -2
B=14,500.
A + 14,500+13,000=55,000
A+27,500=55,000
A=55,000-27,500
A=27,500.
Answer: there are 27,500 seats in section A, 14,500 seats in section B and 13,000 seats in section C. 
        
             
        
        
        
 The answer is:  10 x¹³ y¹⁰  . 
__________________________________________________________
1x^8 *  2y^(10) * 5x^5 = 
1* 2* 5 * x^8 * x^5 * y^(10) = 
10 * x^(8+5) * y^(10) =
10 * x^(13) * y^(10) = 10 x^(13) y^10 ;  write as:
