Answer:

x = 3

y = 9

Step-by-step explanation:

\frac{x}{y} =\frac{1}{3}    →  ( 1 )

  • Use cross multiplication to the above equation.

3x = y   →  ( 2 )

x + y = 12 → ( 3 )

  • Now you can put 3x instead of y to equation (3) according to equation (2).

<u>Let us solve.</u>

x + y = 12

x + 3x = 12

  • And now you can solve the above equation and find the value of x.

4x = 12

Divide both sides by 4.

x = 3

  • Now we can put 3 instead of x to any equation here and find the value of y.

<u>Let us take equation ( 2 )</u>

3x = y

3 × 3 = y

9 = y

Hope this helps you :-)

Let me know if you have any other questions :-)

Answer:

a is drawn to scale, b isn't drawn to scale

Explanation:

a is drawn to scale because 10 cm=5 cm*2 and if measure it that side is exactly two of the 5 cm side. for the 25 cm it should be the same length as the 5 cm side and 20 cm side altogether. B isn't drawn to scale because the 40 cm side should be double the length of the 20 cm side, but it's less than the double the 20 cm side.
