There is so solution to this problem
Answer:
I III and IV
Step-by-step explanation:
You can do
3 * 2 and 11 * 2 which would be 6:22 and is still equal to the ratio 3:11. Your explanation can be the when divided by 2 or the number you multiplied by, you would get the original ratio
Examples:
6:22
9:33
12:44
1.25*(t)+7=43.25
To solve the 2nd one, you must do 43.25 - 7 = 26.25
36.25 divided by 1.25 = 29
Let first consider the equations one by one and will be solving one by one ;

Multiplying both sides by y will lead ;


Now, consider the second equation which is ;

Multiplying both sides by x will yield


As LHS of both equations (i) and (ii) are same, so equating both will yield;

Multiplying both sides by 4 will yield


Dividing both sides by y will yield :

<em>Hence, the required answer is 16</em>
