Answer:

12 + 3x = 27

Step-by-step explanation:

statement: 12 larger than 3 times a number is 27

it translates to

12  larger than   3 times a number  = 27

the equal sign replaces the "is"

let the unknown number be x

so...

12  larger than  3*x = 27

the "larger than"  means plus

so  12 + 3x = 27

HELP ASAP! AGE PROBLEM!! WILL MARK BRAINLIEST!!!
Gennadij [26K]

Answer:

<u>The present age of the mother is 30 years old</u>

Step-by-step explanation:

Age of Jane = x

Age of Billy = 5x (Billy is five times as old as Jane)

Age of Sara = 15x (Their mother is now three times as old as Billy)

In 2 years Sara will be eight times as old as Jane, therefore:

15x + 2 = 8 (x + 2)

15x + 2 = 8x + 16

15x - 8x = 16 - 2

7x = 14

x = 14/7

x = 2 ⇒ 5x = 10x ⇒ 15x = 30

Jane's present age is 2, Billy's present age is 10 and Sara's present age is 30

<u>The present age of the mother is 30 years old</u>
