No, 486×8=3888 so it each student needs to bring in more
= (3/4 + 1/3)/(1/6 + 3/4)
= (3/4 + 1/3)/(1/6 + 3/4)
Multiply numerator and denoiminator by 12
=12(3/4+1/3) / 12(1/6 + 3/4)
= (3*3 + 1*4) / (2 + 3*3)
= 13/11
-5(1 - 5x) + 5(-8x - 2) = -4x - 8
-5 + 25x - 40x - 10 = -4x - 8
25x - 40x + 4x = -8 + 10 + 5 = 7
-11x = 7
x = -7/11
