42 cakes in 7 days, that's 42/7= 6 cakes per day
6*5=30
Well first you would have to do the distributive property... d+4d+ 24=-1. Then you would have to combine like terms. -----> 5d+24=-1------> 24- (-1) =25... now divide 5 from 5 and 25. So d=5... I'm pretty sure this is right...
I need more information for this, the y-axis!
