Question

Tím x

5,5 * ( x + 2,4 ) = 40 - 16,625

Answer 1

5,5 x ( x + 2,4) = 40 -16,625 

                       = 1,85

Answer 2

5,5 *( x + 2,4 ) = 40 - 16,625

5,5*x+5,5*2,4=23,375

5,5*x+13,2=23,375

5,5*x=23,375-13,2

5,5*x=10,175

x=10,175:5,5

x=1,85

Answer 3

=> 5.5 * (x + 2.4) = 23.375

=> x + 2.4 = 23.375 : 5.5 = 4.25

=> x = 4.25 - 2.4 = 1.85

Vậy x = 1.85

Answer 4

5.5 x ( x + 2.4 ) = 23.375

        x + 2.4 = 23.375 : 5.5 

        x + 2.4 = 4.25

                x = 4.25 - 2.4

                x = 1.85

Answer 5

5,5 x ( x + 2,4 ) = 40 - 16,625

5,5 x ( x + 2,4 ) = 23,375

x + 2,4 =  23,375 : 5,5

x + 2,4 = 4,25

x = 4,25 - 2,4

x = 1,85

Answer 6

5,5 *( x + 2,4 ) = 40 - 16,625

5,5*x+5,5*2,4=23,375

5,5*x+13,2=23,375

5,5*x=23,375-13,2

5,5*x=10,175

x=10,175:5,5

x=1,85

Answer 7

  \(5,5.\left(x+2,4\right)=40-16,625\)

\(\Leftrightarrow5,5\left(x+2,4\right)=23,375\)

\(\Leftrightarrow\left(x+2,4\right)=23,375:5,5\)

\(\Leftrightarrow x+2,4=4,25\)

\(\Leftrightarrow x=4,25-2,4\)

\(\Leftrightarrow x=1,85\)

Nhớ ấn đúng cho mình nhé! 

Answer 8

5,5 *( x + 2,4 ) = 40 - 16,625

5,5*x+5,5*2,4=23,375

5,5*x+13,2=23,375

5,5*x=23,375-13,2

5,5*x=10,175

x=10,175:5,5

x=1,85

Answer 9

5,5 x ( x + 2,4 ) = 40 - 16,625

5,5 x ( x + 2,4 ) = 23,375

x + 2,4 =  23,375 : 5,5

x + 2,4 = 4,25

x = 4,25 - 2,4

x = 1,85

Answer 10

5,5 x (x + 2,4) =23,375

x+2,4 = 23 , 375 : 5,5

x + 2,4 = 4,25

x= 4,25 - 2,4 

x=1,85

Answer 11

5,5 * (x+2,4) =23,375 

x+2,4 =23,375: 5,5

x+2,4 =4,25

x=4,25-2,4

x=1,85

nhớ ấn nút đúng ha
