Have you ever been snaked by a friend then ♀️just for the clout❕they’lldo it again .
<span>299.2
The atomic weight of the new element is simply the weighted average of the isotopes. So
0.4030 * 296.78 + 0.5970 * 300.88
= 119.60234 + 179.62536
= 299.2277
Now the number of significant digits is the same as the number of significant digits of the LEAST PRECISE DATUM. And that would be the percentages at 4 significant digits each. So the result needs to be rounded to 4 significant digits which is 299.2</span>

X = 6
Step-by-step Explanation:
(Original problem) 3(2x+8)=60
Multiply 3 to 2x and 8: 6x+24=60
Subtract 24 on both sides of the equation: 6x+24=60
-24 -24
6x=36
Divide both sides by 6: 6x/6 = 36/6
Final result: x = 6
