One centiliter is equal to ten milliliters  so Jason is taking 20 ml of medicine, You multiply 2cl X 10ml = 20ml 
        
             
        
        
        
12.  37,  370,  10^2
13.   20.4, 10^2, 2040
15.   1000*1.75=1750
Hope it helped!

Answer:
-8/7 slope 
Step-by-step explanation:
so first u need to figure out the y=mx+b of ur equation 8x+7y=-28 to make it easier on urself yk. so first you get the y by it self and change it to become 7y= -8x-28 you do this by dragging the 8x to the other side which makes it negative since ur switching sides. now u divide each number by 7 since the 7y is by itself. doing this u get y= -8/7x-4. basically parallel = same slope so you will keep ur same slope or m as -8/7  and now all u need to find is b but in ur question u didnt give coordinates so irdk but ur answer has to have the -8/7 slope
