Answer:
Step-by-step explanation:
Rounding decimals is very simple you just have to follow two steps. First is choosing up to which digit you want to round (target digit) for example you can round to the nearest whole number (23) or the nearest tenth (23.02). Next, you simply have to look at the number after the digit you want to round to and determine whether that digit is bigger or smaller than 5 and do the following.
if it is greater than 5, you round up ... 23.016 => 23.02
if it is less than 5, you round down (target digit stays the same) ... 23.012 => 23.01
if it is equal to 5, you choose ... 23.015 => 23.01 or 23.02
The answer would be x=18. First you set it up by setting up an equation;
166=7x+40. Then you subtract 40 from each side. Last, you divide both sides by 7 and you should get x=166 or 166=x.
