Answer:
x=32
Step-by-step explanation:
8(5/8x+4 = 3/8x+12)
5x+32=3x+96
2x+32=96
2x=64
x=32
So, 9 out of 10 students prefer class, so, obviously, it would not be 100. It would be 150. So in conclusion, 50 students prefer lunch over math class, whilst 150 other students prefer math class over lunch.
The answer to your problem is z=11
So
x- quarters
y - dimes
z- nickels
The system of equations would be
x+10=y
z+5=x
x+y+z= 4.75
