DochEvi [55]

Answer:

700 miles

Step-by-step explanation:

Scale of the map is \frac{1}{2}\textrm{ in}=50\textrm{ mi}

∴ 1\textrm{ in}= \frac{50}{\frac{1}{2}}=50\times 2=100\textrm{ mi}

Distance of Susan from mount Shasha on the map is 7 inch.

Therefore, Number of miles = 7\times 100=700\textrm{ mi}

If the midpoint between (x, 6) and (-9, 14) is (8, 10), find the value of x
Romashka-Z-Leto [24]
Mid point is found by summation of x
Then divide by 2
And same for y

Since mid point for x is 8
So x+(-9) /2 = 8
X - 9 = 16
X=16+9
X= 25
