    11 and 8

    Step-by-step explanation:

    x+y=19

    3x=2+2y

    x=19-y

    3(19-y)=2+2y

    57-3y=2+2y

    55=5y

    y=11

    x=19-11

    x=8

    A= 8

    B=11

    Step-by-step explanation:

    3a=2+2b

    a+b= 19

    a=19 - b

    Substitute a= 19-b to 3a=2+2b

    3(19-b)=2+2b

    57-3b=2+2b

    57-2=2b+3b

    5b=55

    b= 11

    a=19 - b

    a=19 - 11

    a= 8

    The numbers are 3 and 4.

    Step-by-step explanation:

    First, write a formula by allowing x to represent the first number and x+1 will be the second number. Thus, 3x + [2(x+1) + 2] = 19.

    Then, 3x + 2x + 2 + 2 = 19.

    Combining all the similar terms it will give: 5x + 4 = 19.

    Move 4 to the right side of the equation. Thus, 5x = 19 + (-4).

    Simplifying the equation it will be 5x = 15. Then divide both sides of the equation by 5 to get the value of x. 5x/5 = 15/5. Therefore, x = 3.

    Find the value of the other number using equation: x+1. Thus, 3+1 = 4.

    To check if the answers are correct. Replace: x with 3 and x+1 with 4. Thus, 3(3) + 2(4) + 2 = 19. 9 + 8 + 2 = 19. 19 = 19.

    Step-by-step explanation:

    i) -9

    ii)250

    iii) infinite

    iv) You can also call it the test of divisibility for 12. A number is divisible by 12 if the number formed by the last two digits in the number is divisible by 4 AND the sum of the digits in the number is divisible by 3. For example, for 123,456 the last two digits (56) is divisible by 4, AND 1 + 2 + 3 + 4 + 5 + 6 = 21.

    v) What is 35/75 Simplified? - 7/15 is the simplified fraction for 35/75.

    vi) The speed of train is 60 km/hr; find its speed in metres per second.

    Solution:

    According to the problem, we know the speed of the train is 60 km/hr.

    Distance covered in metres;

    1 km = 1000 m

    Therefore, 60 km = 60 × 1000 m

    60 km = 60000 m

    Time taken in seconds;

    1 hr = 60 minutes;

    1 minutes = 60 seconds

    Therefore, 1 hr = 60 × 60 sec

    1 hr = 3600 sec

    Speed = (Distance )/(Time )

    = 60000/3600 metres per second

    To find Speed when Distance and Time are given

    = 16 2/3 metres per second

    vii) 3

    viii) -4

    x) 60°+120° = 180°

    xi) false

    xii) If two circles are equal, then their centre and circumference will coincide and hence, the radii will also be equal. (

    xiii)True.

    xiv) It is given that AB and XY are two terminated lines and both are equal to a third line PQ. Euclid's first axiom states that things which are equal to the same thing are equal to one another
