Answer:
60 miles
Step-by-step explanation:
So if 1 inch = 12 miles, you need to find 4 inches. There are multiple ways to achieve this. However ratios/proportions might be easiest.
if 1/12 = 4/x, x is the value of miles. Cross multiply so you get this:
1 4
- = - = 60 = x
12 x
If x equals 60, that means that 4 inches equals 60 miles on the map.
You could also just find an equal fraction by multiplying the top and bottom both by 4.
Option 2 8-12i is correct.
Step-by-step explanation:
The conjugate of the complex number is obtained by changing the sign of the imaginary part.
In complex number 8+12i
8 is the real part and 12i is the imaginary part
The conjugate of 8+12i is 8-12i
So, Option 2 8-12i is correct.
