Explanation:

When you get this sign “<“ we know that the number in the right side is greater than the number in left side.

So here x is smaller than -10

Answer: x<-10

Step-by-step explanation:

the < in the math equation means that the number to the right is greater than the number to the left. x can not be -10 it has to be lower (smaller).

Answer:

4,151,347,200

Step-by-step explanation:

To find how many ways the train can be made up we use the permutation formula and the values given.

n = 16

k = 9

$_{n}P_{k}=\dfrac{n!}{(n-k)!}$

$_{16}P_{9}=\dfrac{16!}{(16-9)!}$

$_{16}P_{9}=\dfrac{16!}{7!}$

$_{16}P_{9}=4,151,347,200$

So there will be 4,151,347,200 different ways that the train can be made.

Express ln 32 - ln 8 as a single natural logarithm

ivanzaharov [21]

$\bf \textit{Logarithm of rationals}
\\\\
log_a\left( \frac{x}{y}\right)\implies log_a(x)-log_a(y)\\\\
-------------------------------\\\\
ln(32)-ln(8)\implies ln\left( \frac{32}{8} \right)\implies ln(4)$
