If you would like to know which proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps:
200 miles ... 5 inches
50 miles ... x inch = ?
200 * x = 5 * 50
x = 5 * 50 / 200
x = 1.25 inch
The correct result would be <span>x = 5 * 50 / 200.</span>

Answer:
12.5
Step-by-step explanation:
1) Original equation: 3(2) - 18x +225 = 6
2) Simplify: 6 - 18x + 225 = 6
3) Move 18x over to the right: 6 + 225 = 6 + 18x
4) Move the 6 on the right over to the left: 225 = 18x
5) Divide both sides by 18 to isolate x: 225/18, 18x/18
6) x = 12.5
Answer:
k = 143
Step-by-step explanation:
Use the point-slope formula for the equation of a straight line:
y-h = m(x-k), where (h,k) is one of the given points and m is the given slope (-15). Here I'll use the point (-4,k).
y-k = -15(x-[-4]), or y - k = -15(x+4). Now use info from the other point: x=6 and y = -7:
-7 - k = -15(6+4). Here we have enough info to be able to find k.
Solving for -k, we get -k = 7 - 90 - 60, or -k = -143. Then k = 143.
