Traveled hours by a in four years = 120
<span>Traveled hours by b in four years = (120/100) * 120
</span> = 144
Excessive hours traveled by b in 4 years = 144 - 120
= 24
<span>Excessive hours traveled by b in 1.5 years = (24/4) * 1.5
</span> = 9 hours
12
Step by step:
14 1/2=14.5
1 1/4=1.25
14.5 divided by 1.25=11.6
Y = x + 1......slope = 1, y int = 1
y = x + 2.....slope = 1, y int = 2
In y = mx + b form, the slope can be found in the m position and the y int can be found in the b position.
if the equations have the same slope, but different y int, then u have a set of parallel lines which never cross...therefore they have no solution and are inconsistent
Well I don’t know if they made a profit off of helping out, but Karl would have earned $55 if that’s what you are asking.
