Answer:
0.2496
Step-by-step explanation:
what you could do is make the all the 1/5 into 2/10's.
then you could multiply all of them (2/10) squared (2/10) cubed and (2/10)^4
now you would have 2/10 4/100 8/1000 16/10000
now you can change it into decimals and add
0.2 +0.04+0.008+0.0016
now all you have to do is add when you do you get 0.2496
there are many ways you could do this problem but this is the most efficient becuause I used another way but it was not helpfull.
5x+2y = 5.84 is the equation for maddi.
2x+ 8y =10.40 is the equation for stephen.
set them equal and then cancel them out! if you do that you can plug it into the part 2 equation which is
2x+4y+z=4.07
