Well the all paid 10.35×3=31.05 with the tip. The tip is 35.05/100×15=4.6575. To know how much they paid without the tip you just 31.05-4.6575=26.39
Step-by-step explanation:
12x=6-3
12x=3
12x/12=3/12
x=1/4
4x+1=2
4x=2-1
4x=1
4x/4=14
x=1/4
I you have great day
Subtracting 8 from both sides of the equation gives
x^2 + 4x - 12 = 0
(x + 6)(x - 2)= 0
x = -6, 2 answer
