Answer:
If b is 3, x=-1
Step-by-step explanation:
-2(3x-5)=16
use distributive property
-6x+10=16
take 10 away from both sides
-6x=6
divide both sides by -6
x=-1
Here, Mass of one specimen = 0.00063 = 6.3 * 10⁻⁴
Now, Mass of 6 specimens = 6.3 * 10⁻⁴ * 6
= 37.8 * 10⁻⁴ = 3.78 * 10⁻³
In short, Your Answer would be: 3.78 * 10⁻³ Kg
Hope this helps!
