Answer:
y=3x-1 = x=1/3
Step-by-step explanation:
y=3x-1
to find the 0-intercept at x, underline y = 0
0=3x-1
move the variable to the left side and change its sign
-3x=-1
divide both sides of the equation by -3
x=1/3
The value of 7 in 67098 is 7000 and the value of 7 in 74702 is 70000 or 700 so it is either 10 times or 1/10th of the the value.

Mark spend 1 hour 10 minutes in reading.
<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Mark spent 1 hour 17 minutes less than Sheila
Sheila spent 55 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Sheila spent
= 3 hours or (180 minutes) - 55 minutes
= 2 hours 05 minutes.
Now, Mark spent = 2 hrs 05 minutes - 55 minutes
= 1 hour 10 minutes
