Given:

Total distance = 6\dfrac{1}{5} miles

Hiking before lunch = 2\dfrac{2}{3} miles

To find:

How much further does Sylvia have left to hike?

Solution:

Let x be the remaining hiking distance.

We know that,

Total hiking distance = Hiking before lunch + Remaining hiking distance

6\dfrac{1}{5}=2\dfrac{2}{3}+x

\dfrac{(6\times 5)+1}{5}=\dfrac{(2\times 3)+2}{3}+x

\dfrac{30+1}{5}=\dfrac{6+2}{3}+x

\dfrac{31}{5}=\dfrac{8}{3}+x

Isolate variable term.

\dfrac{31}{5}-\dfrac{8}{3}=x

\dfrac{93-40}{15}=x

\dfrac{53}{15}=x

It can be written as

\dfrac{45+8}{15}=x

\dfrac{(3\times 15)+8}{15}=x

3\dfrac{8}{15}=x

So, 3\dfrac{8}{15} miles left to hike.

Therefore, the correct option is C.

write an equation in slope intercept form for the line that is perpendicular to y=-1/4x+2 and passes through the points (-4,3)
PilotLPTM [1.2K]
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:

m1*m2=-1, and in this case:

-m/4=-1

-m=-4

m=4, so the slope of the perpendicular line is 4 so we have thus far:

y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"

3=4(-4)+b

3=-16+b

19=b, so our line is:

y=4x+19
