Answer:
π*AB
Step-by-step explanation:
I m not quite sure about your question because it is lack of details.
However, as my per understanding, Meghan decides to walk along arc AB it means she walks an interval equal to the circumference of the circle AB.
So, apply the formula in caculating the circumference of the circle, we have:
π*d = π*AB
So, she walk a π*AB distance.
Answer:
The car's average 18 number of miles per gallon
Step-by-step explanation:
The car has different efficiencies depending if its used on highway or city streets.
The efficiency on a highway is:

The efficiency for city driving is:

We now that the car uses twice as many gallons for city driving as for highway driving. This means that, for every gallon consumed, 2/3 are for city driving and 1/3 are for highway driving.
Then, we can calculate how many miles makes the car on average as:

B because first you do the two triangles which =3 then you get the area for the square in the middle which is 15 then you add them up to get 18
Answer: y = (x-2)/3
This is equivalent to y = (1/3)x - 2/3
=================================================
To get this answer, we need to swap x and y in the original equation. Then solve for y to get the inverse.
y = 3x+2
x = 3y + 2 ... x and y swapped
x-2 = 3y
3y = x-2
y = (x-2)/3
y = x/3 - 2/3
y = (1/3)x - 2/3
This final equation has slope 1/3 and y intercept -2/3
30 because 18 and the plain goes into 12 which is 30
