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.
Answer:
-16x+14y-45z
Step-by-step explanation:
4x+4y-5(4x-2y+9z)
we apply the distributive property:
4x+4y-5*4x-5*(-2y)-5*9z
so we have:
4x+4y-20x+10y-45z
-16x+14y-45z
