    A. 1

    B. 5

    C. 10

  2. The value of x for which the expressions (x-5) and (2x + 5) becomes equal is ——

    A. 10

    B. -10

    C. 5

  3. If 4x = 10x -6, then the value of x is ———–

    A. 1

    B. 2

    C. 4

  4. The equation for the following statement: Six times y plus 3 gets you 45 is ——

    A. 6y + 3 = 45

    B. 6(y + 3) = 45

    c. 6 + y + 3 = 45

  5. The solution of the equation 3n + 7 = 25 is —————-

    A. 5

    B. 6

    C. 7

    Answer the following:

  6. Solve

    a) 2(m + 2) = 20

    b) 3p – 6 = 21

  7. The sum of three times of a number and 7 is 37. Find the number?
  8. Set up equation and solve

    a) Manu takes a number such that half of the number is 5 more than 21.

    b) Amina thinks of a number. If she takes away 2 from three times of the number, the result is 25.

  9. Convert the following statements into equations:

    a) Three times the sum of 8 and the number y is 42.

    b) 7 subtracted from twice a number y is 21.

  10. Solve the following equations:

    a) 3y + 5 = 44

    b) 3(m + 3) = 18

ANSWERS:

  1. 5
  2. -10
  3. 1
  4. 6y + 3 = 45
  5. 6
  6. a) 2(m + 2) = 20

    m + 2 = 20/2

    m + 2 = 10

    m = 10 – 2 =8.

    b) 3p – 6 = 21

    3p = 21 + 6 = 27

    p = 27/3 = 9

  7. Let the number be x.

    Given 3x + 7 = 37

    3x = 37 – 7

    3x = 30

    x = 30/3 = 10.

    8.a) Let the number be x.

    Given ½ x = 5 + 21

    ½ x = 26

    x = 26 x 2 = 52.

    b) Let the number be x.

    3x – 2 = 25

    3x = 25 + 2 = 27

    x = 27/3 = 9

    9.a) 3( 8 + y) = 42

    b) 2y – 7 = 21

    10.a) 3y + 5 = 44

    3y = 44 – 5

    3y = 39

    y = 39/3 = 13.

    b) 3(m + 3) = 18

    m + 3 = 18/3

    m +3 = 6

    m = 6 – 3 = 3.

Roland Barthes’ Theory of Five Codes

Roland Barthes’ Theory of Five Codes According to Roland Barthes,   all narratives share structural features that each narrative weaves together in different ways. Despite the differences between individual narratives, any narrative employs a limited number of organizational structures (specifically, five of them) that affect our reading of texts. Rather than seeing this situation as limiting, however, Barthes argues that we should take this plurality of codes as an invitation to read a text in such a way as to bring out its multiple meanings and connotations. Rather than reading a text for its linear plot (this happens, then this, then this), rather than being constrained by either genre or even temporal progression, Barthes argues for what he terms a "writerly" rather than a "readerly" approach to texts. According to Barthes, "the writerly text is   ourselves writing , before the infinite play of the world (the world as function) is traversed, inters...

'The Bus' by Arun Kolatkar: Summary and Analysis

'The Bus' by Arun Kolatkar: Summary and Analysis Summary:   'The Bus' by Arun Kolatkar is the opening poem of the thirty-one section of his collection of poems 'Jejuri.' It describes the bumpy journey from the starting point to its destination which is the temple of Khandoba. It is a State Transfort bus the windows of which are screened by the tarpaulin with which the bus has been covred to keep the possible rainfall , and also to keep off the cold wind which keeps blowing throughout the journey. It is a night journey which the bus has undertaken ; and after several hours of the arduous journey the passengers start waiting eagerly for daybreak.  The bus is full of the pilgrims who are bound for the temple of Khandoba where they want to offer worship; and the passengers might have included a few tourists who merely want to satisfy their curiosity about what kind of a temple it is and in what surroundings the temple stands. One of the passengers sits op...

“A Hot Noon in Malabar' by Kamala Das: Summary and Analysis

“A Hot Noon in Malabar' by Kamala Das: Summary and Analysis The poetess recalls some of her experiences in her home in Malabar. She thinks of the hot noon-time when all sorts of persons used to pass her home and to pause and to stop there in order to sell the wares which they carried from place to place. She first thinks of the beggars who used to come to her house to beg alms in their characteristic voices expressive of their discontent with life and their need for charity.  Then she thinks of the men who came from the hills with parrots in a cage and fortune-cards, all stained because of the long time during which those cards had been used again and again. She thinks of the brown-complexioned girls who belonged to the class of basket-makers and manufacturers of bird-catching traps. These girls were palm-readers who offered, in their monotonous voices, to read the palms of those who wanted their fortunes told on the basis of the lines on their palms.  The poetess then...
