Sarah was thinking of a number. Sarah doubles it, then adds 4 to get an answer of 97.7. What was the original number?

Sagot :

Answer:

46.85

Step-by-step explanation:

let the number be n then doubling it is 2n and

2n + 4 = 97.7 ( subtract 4 from both sides )

2n = 93.7 ( divide both sides by 2 )

n = 46.85
