Answer:

108 ft

Step-by-step explanation:

The total length in inches of the perimeter of the model is ...

7 in + 3 in + 3 in + 5 in = 18 in

The total length of the walkway will have the same ratio to this perimeter that the corresponding sides have:

EF/AB = 42 ft/(7 in) = (walkway length)/(18 in)

Multiplying by 18 in, we get ...

walkway length = (42 ft)(18 in)/(7 in)

walkway length = 108 ft

-BARSIC- [3]

Answer:

(3,10) is not a solution of the given system.

Step-by-step explanation:

Testing the point (3,10) for the system of inequalities, where 3 is the x coordinate, and 10 the y-coordinate, then:

$\left\{\begin{matrix}y &> 2x+3 & \\y& 2(3)+3\Rightarrow 10>9 \: False\\10>3(3)+1\Rightarrow 10 >10 \: False$

So the point (3,10) is not a solution of the given system.
