The scale of a map is 4 meters = 18 miles. The distance on the map is 6.8 meters. Find the actual distance in miles.

30.6 miles

Step-by-step explanation:

Scale of map: 4 meters=18 miles

Equation: 4x=18 x=18/4 or 9/2

Now, 9/2*6.8=30.6

I'm not sure if it's correct!

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
