Haruka hiked 14 kilometers in all.
Step-by-step explanation:
Given,
Distance hiked in afternoon = 6 kilometers
It was 25% less than Morning.
Let,
x be the distance hiked in morning;
x-25% of x = 6
Dividing both sides by 0.75
She hiked 8 kilometers in morning.
Total distance hiked = Distance in morning + Distance in evening
Total distance hiked = 8+6 = 14 kilometers
Haruka hiked 14 kilometers in all.

Answer:
x = 2
Step-by-step explanation:
the equation of the line can be found using the slope intercept form
y = mx +b
y= -3/2 x + 3
x intercept is found by setting y=0 bc that will give you the x-value at which the line crosses the x -axis so
0 = -3/2x+3 (subtract the 3 on both sides) would cancel out the + 3 and would
-3 = -3/2 x (divide by -3/2 on both sides to cancel out the -3/2)
x = 2
