Answer:
the answer is 9
Step-by-step explanation:
-3.5y - 6.2y = - 87.3
or, -9.7y = -87.3
or, y = -87.3/-9.7
or, y = 9.
So the distance between subway stop and house is 19 units
Step-by-step explanation:
The distance formula will be used to calculate the distance between home and subway.

Here (x1,y1) are the coordinates of first point
and
(x2,y2) are the coordinates of second point
Given
(x1,y1) = (7, -6)
(x2,y2) = (-9,5)
Putting the values in the formula

Rounding off to nearest unit gives us 19.
So the distance between subway stop and house is 19 units

3(5j+2)=2(3j-6) do distributed to remove parenthesis 15j+6=6j-3 . Then move all j to left side and the second term to right side 15j-6j=-3-6. Now solve both sides 9j= -9. Now divide both sides by 9 to get j alone to j = -1
Well, the first one is 2/40=1/20. The 2nd one is 1/39. You multiply these to get 1/780.
