Answer:
The scale factor is -1/4.
Step-by-step explanation:
Answer:
the interquartile is 4
Step-by-step explanation:
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>
To find the answer to this question, we need to find the common denominator for 3/5 and 2/3.
The easiest way to do this is to multiply the denominators by each other.
5*3=15
Now, all we have to do is multiply the numerators by what we multiplied the denominators by, to make it equal.
3*3=9
2*5=10
Now all we have to do is add.
9/15+10/15=19/15 or 1 and 4/15.
Hope this helps!
