What is 3.4 / x = 2.17/ 7.7?

You could use a method called cross products to solve this proportional equation.  What you would do is multiply 3.4*7.7 =2.17*x

If multiplied correctly, your equation should be 26.18 = 2.17x

You are trying to get the variable alone on one side.  To do this, you have to undo the multiplication of the coefficient.  The opposite of multiplication is division, so you would divide both sides by 2.17.

If done correctly, your equation should now be x=<span>12.064516129

However, this can be rounded to x= approximately 12.066

Someone could help me out to find the answer thanks​

Answer:

  h(x) = 11/(x -4)

Step-by-step explanation:

The domain of m(x) is restricted to x≠1. That means the domain of m(n(x)) must be restricted so that n(x)≠1, or x≠4.

The only offered choice with a domain restriction x≠4 is the 3rd choice:

  h(x) = 11/(x -4)

Answer: 14.48000 . . . ≤ t < 15.0000

Step-by-step explanation:

"Truncated by a hundreths of a second" means that the time was rounded to the nearest 0.0X second.  That would mean the reported time of 14.48 seconds was shortened from a time period having more digits to the right.  For example, If the time were actually 14.48223 seconds, the time was truncated to just 14.48 seconds.  The term used here. truncated, means that the digits after the hunredth place are simply dropped.  It doesn't say rounded, just truncated.  Brutal.  So that would mean that times between 14.48000 . . . and 14.48999 . . . would all be reported as 14.48 seconds.

So the time could actually be 14.48000 . . . ≤ t < 15.0000
