A 50g piece of chocolate costs 45p. How much would 1kg of chocolate cost at this rate?

Step-by-step explanation:

Cost of 50g of chocolate= 45 p

cost of 1 g of chocolate = 45/50 p. = 0.9p

cost of 1kg = 1000g = 0.9* 1000 p

= 900 p

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
