Answer:
The standard form of this equation is -8x + 3y = -68
Step-by-step explanation:
In order to find this, first solve for the constant.
y = 8/3x - 68/3
-8/3x + y = -68/3
Now we multiply by 3 to get them all equal to integers.
-8x + 3y = -68
Write a proportion
centimeters / kilometers
1.5 / 45 = 0.8 / x
cross multiply
(1.5 * x ) = (45 * 0.8)
1.5x = 36
divide both sides by 1.5
x = 24
The actual distance between the two points is 24 kilometers.
Hope this helps
