"When it bonged eleven times I was past feeling" is an example of which literary device? (Inside of to kill a mockingbird by harper lee)

That would be an onomatopoeia, the use of words which sound like what they describe. ("bonged" in this context)

Explanation: "Bonged" is describing a sound.

d

explanation:

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
