Answer:

D= -10

an=a+(n-1)d

a100=-30+(100-1)-10

a100=-30+99x-10

a100=-960

(n/2)(A1+an)

(100/2)(-30-960)

(50)(-990)

= -49500

Answer:

150 miles

Step-by-step explanation:

let m represent miles

$70 + .70m = $40 + .90m

subtract 40 from each side

$30 + .70m = .90m

subtract .70m from each side

$30 = .20m

divide both sides by .20

150 = m
