White flour makes up 2 / (2+3) of the total 10 cups: 2/5 of the total 10 cups.
2/5 times 10 is 4 cups.
You'll need 4 cups white flour and 6 cups whole wheat flour, making a total of 10 cups of flour.
It is 8y4 becuze 8*2=64 and 4*2=16 and u *2 becuze *2 means square root sorry if I'm wrong :)
1 gallon is $4.20
16.80/5=4.20
I just took that quiz on k12. The answer is no solution. Hope I helped!
