Josh earned $72 less than his sister who earned $93 more than her mom. If they earned a total of $504, how much did josh earn

I'm assuming when you say the total of $504 you mean just between Josh and his sister? If so, Josh earned $216 and his sister earned $288

Step-by-step explanation:

Set each person in terms of X. If Josh's sister earned $93 dollars more than her mom, set the equation as (x+93). Since Josh earned $72 less than his sister, he essentially earned 21 dollars more than his mom (x+21). Add those two equations together and set them equal to $504 dollars. Solve for X and solve each equation individually with your answer to find how much each earned.

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
