Answer:
Step-by-step explanation:
soulution:
         given,              2x +2x = 16 <em>-</em> <em>2x</em> + 3y = 14
                                  2x <em>+ 2x</em> = <em>-2y </em>+3y = 14 -16
                                        4x = y = -2
                                          y = 4x = -2
                                           y = x =  4/-2
                                          x = y =  <u><em>-2 ans</em></u>
 
        
             
        
        
        
162/(6(7-4)^2)
pemdas
parenthasees inner first
so 7-4 is forst
7-4=3
162/(6(3)^2)
then exponents
3^2=9
162/(6(9))
multiplication
6 times 9=54
162/(54)=3
        
             
        
        
        
Both servings of pancakes cost $8.50
One serving of pancakes cost $4.35
Equation:   1.15 (2x + 1.50) = 11.50
                   2.3x + 1.725 + 11.50
                    2.3x = 9.725
                    x = 4.25 for one serving of pancakes
                    2x = 8.50 for both servings of pancakes
 
        
             
        
        
        
Answer:
<u><em>A</em></u>
Step-by-step explanation:
<u>a)</u>
<u></u> <u></u>
<u></u>
<u>8(9) / 9 = 8 x 7 = 56</u>
b)

2(9) * 3 - 12
18 * 3 = 54 - 12 = 42
c)

4(9) - 18 + 12
36 - 18 = 18 + 12 = 30
d)

21 + 24 = 45
