Here are the rates of the trains:
(n represents train A's speed)
A: n

We have to write the algebraic expression for:Here, the number is unknown term, so x represents the number.

Now according to given information ,

One - eight of the sum of a number and three.

→ \frac{1}{8} of the sum of x and 3

→ \frac{1}{8} \times (x + 3)

→ \frac{x+3}{8}

→ \frac{x}{8}+\frac{3}{8}

Hence the algebraic expression for one-eight of the sum of a number and three is \frac{x}{8}+\frac{3}{8}

1/5,1/10,0,_1/10 ...find arthmetic sequence
Papessa [141]
A = 1/5
d = T2-T1
d = 1/10 - 1/5
d = 1/10 - 2/10
d = - 1/10

T4 = 1/5 + 3(-1/10)
= 1/5 - 3/10
= 2/10 - 3/10
= - 1/10
