Find the HCF of
18x²y3 and 6y?

The answer should be: 18 and 24, if someone could give me some advice that would be great.

Step-by-step explanation:

Prime factorize

18x² y³ = 2 * 3 * 3 * x² * y³

6y = 2 * 3 *  y

HCF = 2* 3 * y = 6y

$4

Step-by-step explanation:

let t represent teddy bear and v represent vase, then

2t + 3v = 27 → (1)

3t + 2v = 30.5 → (2)

Multiplying (1) by 3 and (2) by - 2 , then adding will eliminate t, that is

6t + 9v = 81 → (3)

- 6t - 4v = - 61 → (4)

Add (3) and (4) term by term to eliminate t, that is

5v = 20 ( divide both sides by 5 )

v = 4

The cost of the flower vase is $4
