Are 25 milligrams lighter or heavier than 25 centigrams

masya89 [10]

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth. So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Eddi Din [679]

Answer:

x = $\frac{9}{80}$

Step-by-step explanation:

x + $\frac{9}{20}$ = $\frac{9}{16}$

Multiply through by 80 ( the LCM of 20 and 16 ) to clear the fractions

80x + 36 = 45 ( subtract 36 from both sides )

80x = 9 ( divide both sides by 80 )

x = $\frac{9}{80}$

How do I solve this. Log 5x = log (2x+9)

liubo4ka [24]

$D:5x\ \textgreater \ 0 \wedge 2x+9\ \textgreater \ 0\\
D:x\ \textgreater \ 0 \wedge 2x\ \textgreater \ -9\\
D:x\ \textgreater \ 0 \wedge x\ \textgreater \ -\dfrac{9}{2}\\
D:x\ \textgreater \ 0\\\\
\log5x=\log(2x+9)\\
5x=2x+9\\
3x=9\\
x=3$
