Translate and simplify number 10

Answer 1

Answer:

The number is 2,5

Step-by-step explanation: For solve this problem we have to made a polinomial function as follows:

We know that is a half number that means X/2, the next step we have to decrese by 8, $\frac{X}{2}$-8, finally the result is (-3).

$\frac{x}{2}$ -8=-3 ⇒ $\frac{x}{2}$=-3+8

$\frac{x}{2}$=5 ⇒ x=$\frac{5}{2}$ or x=2.5
