Answer:
Square root of 4 is 2
so 1+=4
frac{[1+sqrt{2x-1]}^2 }{4}=3
so 1+sqrt{2x-1]}^2=12
so 1+sqrt{2x-1}=V12
sqrt{2x-1}=V12-1
2x-1=(V12-1)^2=12-2V12+1=13-2V12
2x=13+1-2V12
2x=14-2V12
x=7-V12
x=7-2V3

Step-by-step explanation:
6 / 5/9
First turn 5/9 into decimal form.
5 / 9 = 0.55555555555555555555555555555556
Then divide 6 by 0.55555555555555555555555555555556
6 / 0.55555555555555555555555555555556 = 10.8 or 10 8/10 or 10 4/5

Let x be the number of hours to fix car.
$80x + 210 = 490
80x= 490-210
80x = 280
x = 280/80
x= 3.5 hours
