X=soy beans
y= wheat
x= 5y (because soy beans cost five times as much as wheat)
4.7x+2.4y= $51.80
Substitute x=5y
4.7(5y)+2.4y=51.80
23.5y+2.4y=51.80
25.9y=51.80
Divide both sides by 25.9
y=$2 cost of wheat per pound
x= 5y
=5(2)
=$10 cost of soy beans per pound
Check:
4.7x+2.4y= $51.80
4.7(10)+2.4(2)=51.80
47.0+4.80=51.80
51.80=51.80
Hope this helps! :)
It would be 6/20 = $0.30
30 cents or $ 0.30
Step-by-step explanation:
Let the sum of rupee be x
no of boys be y
then each boy get x/y
now if the no of boys increased by 10 each boy get x/(y+10) = (x/y)-1 => x/(y+10) = (x-y)/y .........(1)
now case 2nd if no of boys decrease by 15 each boy get x/(y-15)= (x/y) +3 => x/(y-15) = (x+3y)/y ...........(2)
1) 4.5 T = 9,000 lbs
2) 3 T 427 lbs = 6,247 lbs
Hope this helps! I’m pretty sure they’re both correct
