I left Pickton in my car at 8.30 am, just as a bus from Orford was pulling into the bus station. The buses leave Orford for Pickton at 30-minute intervals. 10 minutes later, another Orford-Pickton
bus passed me
Assuming that both the buses and travel at constant
speeds, which one or the following
additional pieces of information do I need in order to know when I will arrive at Orford?
A
The distance from Pickton to Orford,
B
The bus's average speed.
с
My average speed
The bus journey time for Orford to Pickton.
D

●yes, this statement is absolutely apt.

hope this you

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a

1/4(-5+n) < 20 the opposite of 5-n is -5+n

multiply by 4

-5 + n < 80

+ 5

n< 85
