Answer:

x=35.35

Step-by-step explanation:

If you multiply $\frac{x}{10.1} .1$ by 10.1 that will cancel out the 10.1s, then since you multiplies one side of the equation by something you have to multiply the other too. So 3.5*10.1 = 35.35. Then since the 10.1s canceled out this leaves us with x=35.35. Let me know if you need any more help.
