an =a1+d(n-1)

where d is the common difference

d=5-8

d=-3

a1=8

an =8-3(n-1)

Find the value of x. Will give brainliest.

s344n2d4d5 [400]

Since a line is equal to 180 degree
you pick one that has the variable x in it.
For example: 5x=180
180/5=36
therefore x=36
2. 6x=180
180/6= 30
x=30

Answer:

y=50x

Step-by-step explanation:

distance = 50 times the laps

100= 50 x 2

200 = 50 x 4

250= 50 x 5

400 = 50 x 8
