Choose the pair of numbers that is not a solution to the given equation.

y = 5 - 2x

(1, 3)
(2, 1)
(0, 3)

The answer to this would be (0,3), Since if we were to replace the values and change 2(x) to 2(0) and change Y to (3) the equation would be false. 3=5-0 which simplifies to 3=5.. That's false and impossible. 1=5 - 2(3) is true because 2x3 equals 6 and 5-6 equals 1 which is true. So that eliminates A).Now 2=5-2(1) would be 2 x 1 equals 2 and that simplifies to 2=5-2 which is basically 5-2 and that would simplify to 3 which would be 2=3 this is false now if we change the X & Y and make into 1=5-2(2) which would be 2x2 equals 4 and now 4-5 equals 1 this is true! (0,3) Regardless of placement is still false. Let me know if you need me to explain more. Hope this helped you :)

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
