Answer:
0.0005123
Step-by-step explanation:
The scientific notation 5.123e-4 is same as 5.123×10^-4 or 5.123×10-4. Thus, to get the answer to 5.123e-4 as a decimal, we multiply 5.123 by 10 to the power of -4.
= 5.123e-4
= 5.123 × 10-4
= 0.0005123
8 - 7x - 3 = 19
5 - 7x = 19 |subtract 5 from both sides
-7x = 14 |divide both sides by (-7)
x = -2
