Question

a number tripled and then 30 is subtracted from it.when the resulting number is divided by 15, we get the number 8. find the number​

Answer 1

Answer:

50

Step-by-step explanation:

Let the number be x

three times of the number is 3x.

When 30 is subtracted it will become 3x-30

on dividing 3x-30 by 15, we get 8

⇒(3x-30)÷15 =8⇒3x-30 =15×8

3x-30 = 120⇒3x =120+30 ⇒3x =150

x =50

Answer 2

Answer:

50

Step-by-step explanation:

let the number be x,

number is tripled= 3x

30 is subtracted 3x-30 and the result is divided by 15

so (3x-30)/15 = 8

on solving we get

3x-30= 120

3x= 150

x= 50

so the number is 50
