He ran. he jumped. he won the race. which one of these rhetorical devices is used here? a. metaphor b. simile c. parallelism d. personification

Parallelism.

Metaphors and similes are used to relate one thing to another; this sentence is not doing that. Parallelism is when similar devices are used in sentences to convey one story.

i learn slow so it would take me like awhile

i hope i was so kinda

and if i was you in would goggle it and watch videos or go to your friends and ask them or maybe even your teacher for extra

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
