Alex was thinking of a number. Alex adds 9.8 to the number, then doubles the result to get an answer of 90.9. Form an equation with x from the information.

Respuesta :

Answer:

2(x+9.8)=90.9

Step-by-step explanation:

let's represent the number with x.

9.8 is added to x, and then that is doubled to get 90.9.

therefore, we put x+9.8 in parenthesis and then multiply that by 2 since it says that the result of x+9.8 was doubled. we set that equal to 90.9 since it's stated that the result of 2(x+9.8) is equal to 90.9

2(x+9.8)=90.9
