The scale on the map shows that 2 inches represents 15 miles. which proportion can be used to find the actual distance x, represented by 30 inches on the map

The actual distance represented by 30 inches is x = 225 miles

Step-by-step explanation:

Here, in the given scale:

2 inches represents 15 miles.

Let us assume 30 inches represent  x miles.

Now, as given  2  inches  = 15 miles

1 inch miles

So, 30 inches  = 30 x (7.5 miles) = 225 miles

⇒ 30 inches  = 225 miles

Hence, the actual distance represented by 30 inches is x = 225 miles

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
