x + 2y - 3.5

Step-by-step explanation:

Because the only operation to be used is addition, the parentheses can be taken away:

(x - 5) + (2y - 3.5) + (-x + 5)

x - 5 + 2y - 3.5 + -x + 5

Addition of negative numbers is subtraction:

x - 5 + 2y - 3.5 + -x + 5

x - 5 + 2y - 3.5 - x + 5

Combine like terms to find the furthest simplification of the equation:

x - 5 + 2y - 3.5 - x + 5

x - 5 + 2y - 3.5 + 5

x + 2y - 3.5

Finally, simplify the coefficient of x:

x + 2y - 3.5

x + 2y - 3.5

(x - 5) + (2y - 3.5) + (-x + 5) = x + 2y - 3.5

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

i believe the answer is 323 ft
