Answer:
Step-by-step explanation:
the median for 35 values, you can cross the first one and last one until there is only one value left, with should be the 18ᵗʰ value
the median for 36 values, same thing, but after cross all, there will be 2 values left instead of 1, just find the mean between 2 values.

Answer:
x = 9
Step-by-step explanation:
when two lines intersect, it creates four angles. vertical angles are the angles that are opposite to each other. in the attached image, 1 & 3 are vertical angle pairs, and so are 2 & 4.
since vertical angles are always congruent, 3x - 8 is equal to 2x + 1
3x - 8 = 2x + 1
add 8 to each side
3x = 2x + 9
subtract 2x from each side
x = 9
check your answer:
3x - 8 = 2x + 1
3(9) - 8 = 2(9) + 1
27 - 8 = 18 + 1
19 = 19
