Step by step workout of ; log x^3+log 5x=5 log 2-log 2/5

Charra [1.4K]

Answer:

x = 2

Step-by-step explanation:

$log \: {x}^{3} + log \: 5x = 5log \: 2 - log \: \frac{2}{5} \\ \\ \therefore \: log( {x}^{3} \times 5x) = log {2}^{5} - log \: \frac{2}{5} \\ \\ \therefore \: log( 5{x}^{4}) = log 32 - log \: \frac{2}{5} \\ \\ \therefore \: log( 5{x}^{4}) = log \bigg(32 \times \frac{5}{2} \bigg) \\ \\ \therefore \: log( 5{x}^{4}) = log \bigg(16 \times 5) \\ \\ \therefore \: 5{x}^{4}= 16 \times 5 \\ \\ \therefore \: {x}^{4}= {2}^{4} \\ \\ \huge \purple{ \boxed{\therefore \: {x} = 2}}$

Simplifying fractions:

1) $\frac{14}{20} =\frac{7}{10}$ 2) $\frac{4}{8} =\frac{1}{2}$

3) $\frac{9}{12} =\frac{3}{4}$ 4) $\frac{12}{15} =\frac{4}{5}$

5) $\frac{8}{18} =\frac{4}{9}$ 6) $\frac{14}{21} =\frac{2}{3}$

7) $\frac{12}{16} =\frac{3}{4}$ 8) $\frac{10}{24} =\frac{5}{12}$

9) $\frac{15}{35}=\frac{3}{7}$ 10) $\frac{13}{26} =\frac{1}{2}$

11) $\frac{11}{55}=\frac{1}{5}$ 12) $\frac{9}{21} =\frac{3}{7}$

13) $\frac{16}{26} =\frac{8}{13}$ 14) $\frac{20}{32} =\frac{5}{8}$

15) $\frac{18}{24} =\frac{3}{4}$ 16) $\frac{21}{27} =\frac{7}{9}$

17) $\frac{4}{32} =\frac{1}{8}$ 18) $\frac{25}{40} =\frac{5}{8}$

Which expression is equivalent to 4x+3x+4-2x

kvv77 [185]

Answer:

5x+ 4

Step-by-step explanation:

First, put all of the x variables together. So 3x+4x=7x

7x + 4 -2x Since the 2x is negative you can subtract it from 7x and get 5x.

you can not add the four to the 5x because it does not have a matching variable.

So, you have: 5x+ 4

Find the mean and the median of this data set: 9 6 4 3 28 6 4 7

storchak [24]

Answer:

the median is 6 and the mean is 8.375

Step-by-step explanation:

first you have to arrange the numbers from least to greatest the median is the middle number which in this case there are two but both of them are 6 so the median is 6 and for the mean you just average by adding it all together then divide by the total
