Solve 4(2x/3+8)=40 X=?

Side note: 2x/3 is a fraction

9514 1404 393

  x = 3

Step-by-step explanation:

Undo what has been done to the variable.

  4(2x/3 +8) = 40

  2x/3 +8 = 10 . . . . . divide by 4

  2x/3 = 2 . . . . . . . . . subtract 8

  x = 3 . . . . . . . . . . . . multiply by 3/2

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

80 the answer is 80
