Answer:
X=1/2. X=4/3
Step-by-step explanation:
6x2+5X-4=0
6X2+8X-3X-4=0
2x(3x+4) - 1(3x+4)=0
2x-1) (3X-4)
X=1/2. X=4/3
10/1 = 43.5/x
cross multiply
10x=43.5
divide by 10 on each side
x = 4.35
it will take 4.35 minutes
51/4 because you multiply 12*4 which is 48 and add 3 so you get 51. You keep the denominator so you should get 51/4.
