546000 u look at the number on the right and if it is greater than 5 u add 1
Answer:
857
Step-by-step explanation:
70th term = a + d(n-1)
d= 29-17=12
a=29
n-1 = 69
70th term = 29 + 12×69
= 29 + 828
= 857
Total was 200
x+y=200
biking was 40 mor than bus
x=40+y
subsitute 40+y for x in other equation
x+y=200
40+y+y=200
40+2y=200
minus 40 both sides
2y=160
divide both sides by 2
y=80
sub back
x=40+y
x=40+80
x=120
120km biked
80km on bus
