Yellowstone Lake, in Wyoming, is the largest high-altitude lake in North America, measuring 20 miles long and 14 miles wide. How long and wide would Yellowstone Lake appear on a map with the scale 1 inch = 3 mi?

6.67in long and 4.67in wide

Step-by-step explanation:

Given the amp of the scale 1 inch = 3 mi?

If the measured length is 20miles

Let x be the dimension of the length on the map

1 inch = 3 mi?

x = 20miles

3x = 20

x = 20/3

x = 6.67in

For the width,

Width =14miles

Let y be the dimension of the width on the map

1 inch = 3 mi

y = 14miles

3y = 14

y = 14/3

y = 4.67in

Hence the Yellowstone Lake appears 6.67in long and 4.67in wide on the Map

xcvb nm you ugly

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
