Caroline was thinking of a number. Caroline doubles it, then adds 13 to get an answer of 15.1. What was the original number?​

Answer 1

Answer:

PLEASE MARK IT AS BRAINLIEST

Let the n.o be x.

given doubles it => 2x

adds 13 => 2x +13 =15.1

therefore 2x = 2.1

x= 2.1/2 = 1.05

Answer 2

Answer:

As the answer is 15.1

therefore,

15.1-13=2.1

and

as the no.was doubled so

2.1÷2=1.05
