Answer:

x = 50

Step-by-step explanation:

log_{10}(2x)  = 2

Use the following property.

log_{a}(m)  = n \\  {a}^{n}  = m

{10}^{2}  = 2x \\ 100 = 2x \\  \frac{100}{2}   = x \\ 50 = x

Therefore, the value of x is 50.

<u>Answer</u><u> </u><u>Check</u>

Substitute x = 50 in the equation.

log_{10}(2x)  = 2 \\  log_{10}(2(50))  = 2 \\  log_{10}(100)  = 2 \\  {10}^{2}  = 100 \\ 100 = 100

The equation is true. Therefore x = 50.

<u>Note</u>

If you don't write logarithm with base, it is classified as common logarithm or base 10.

The clownfish kay wanted to buy for $12 last week has been marked up 8%. What is the new price of the fish?
Crank
The markup is 8%, meaning it costs 8% more.
The starting price is 100%.
Therefore, the markup is 108% of $12.
If we multiply 12 by 108% (1.08), we will get our answer of $12.96

Nancy leaves the school and drives toward her town at 27 mph. greg leaves the same school 2 hours later and drives the same rout
Paul [167]
Nancy's rate=27 mph
Greg's rate=45 mph
t=Greg's time
t+2=Nancy's time
Since they both traveled same distance then:
27(t+2)=45t
27t+54=45t
18t=54
t=3 hours
Greg will pass Nancy after 3 hours
