K=2

Step-by-step explanation:

If you have the equations 5+2k=9 you would have subtract 5 from both sides and be left with 2k=2 then you would have to divide by 2 to get k  by itself to get k=2

What is the solution to log Subscript 2 Baseline (9 x) minus log Subscript 2 Baseline 3 = 3
sdas [7]

The value of x is  \frac{8}{3}

 Explanation:

The expression is  \log _{2}(9 x)-\log _{2}(3)=3  

Adding  \log _{2}(3) to both sides of the equation,  we get,

\log _{2}(9 x)=3+\log _{2}(3)

Using log definition, if  \log _{a}(b)=c  then  b=a^{c} , we have,

 9 x=2^{3+\log _{2}(3)}

Using exponent rule, a^{b+c}=a^{b} a^{c},

9x=2^{\log _{2}(3)} \cdot 2^{3}

Simplifying, we have,

9x=3\cdot8\\9x=24

Dividing both sides by 9, we have,

x=\frac{24}{9}

Simplifying,

x=\frac{8}{3}

Thus, the value of x is \frac{8}{3}

You roll a six-sided number cube and flip a coin. What is the probability of rolling a number less than 2 and flipping heads? Wr
Pie

Answer:

\frac{1}{18}

Step-by-step explanation:

As the six-sided number cube had six sides, there are six events which could occur. There is only one interger less than 2 (1), therefore the probability of rolling a number less than 2 is \frac{1}{6}.

There are two events which could occur when flipping a coin. This means the probability of flipping heads is \frac{1}{2}.

To find the probability of both of these happening, you must multiply the fractions together by multiplying together both the denominators and numerators, therefore:

\frac{1}{6} ×  \frac{1}{2} = \frac{1}{18}
