Question

3) Find the solution of 3n-1 = 17.
4) Find the ratio of 400g to 2.4kg.​

Answer 1

Answer:

Step-by-step explanation:

3) 3n - 1 = 17

⇒ 3n = 17 + 1

⇒ 3n = 18

⇒ n = 18/3

⇒ 6

4) 2.4 kg in g is 2400g

⇒ 400g : 2400g

⇒ 400/2400 ⇒ 1/6 ⇒ 1 : 6

Answer 2

Answer:

(1) 3n-1 =17

   3n    =17+1

   3n    =18

    n     =18/3

     n    =6

(2)  400g:2.4kg

    =400:2400

    =1  :  6
