Hope this helps, LMK if its right
The border is the perimeter of the scarf.
P= 2(4+1)
= 10
The border of the scarf should be covered by 10 feet.
If 3mile=28 min
x mile=42 min
cross multiply
x=3/28
therefore if 3/28=1 min
then x mile= 42 min
cross multiply
42 x 3/28 =21 x 3/14
=3 x 3/1
=9
The answer is 9 miles
First, distribute.
{8x-11(x-2)=-8}
{8x-11x+22=-8}
Next, add up the variables.
{8x-11x+22=-8}
{-3x+22=-8}
Then, move 22 to the other side.
{-3x+22=-8}
{-3x=-30}
Finally, divide each side to get your answer.
{-3x=-30}
<em>x=10</em>
