q12 is 8

q13 is 81

Step-by-step explanation:

100*6 =600 / 75 = 8

90*72 = 6480 / 80 = 81

Answer 2

Answer:

$x=8 , w=106.$

Step-by-step explanation:

To find this answer, it is quite simple. This is because you use to cross multiply rule in order to solve the problem so you multiply

$100*6, 75*x$ and you get 600=75x. Then you solve the equation like normal. Same thing for the second equation 90*72 and 80*w you will get 6480=80w. And then solve the equation from there. I hope this helps :)))
