Answer:

x =   \frac{5}{48}

Step-by-step explanation:

\frac{2}{5}  +  \frac{1}{x}  = 10 \\  \frac{1}{x}  = 10 -  \frac{2}{5}  \\  \frac{1}{x}  =  \frac{50 - 2}{5}  \\  \frac{1}{ x }  =  \frac{48}{5}  \\ use  \:  \:  \:  \: cross \:  \:  \:  multiply \\ 5 = 48x \\  \frac{5}{48}  =  \frac{48x}{48}  \\ x =   \frac{5}{48}    \\

Mr. Wilson invested money in two accounts. His total investment was $20,000. If one account pays 5% in interest and the other pa
blagie [28]

a = amount invested at 5%

b = amount invested at 2%

now, we know the total invested by Mr Wilson was 20000, so whatever "a" and "b" might be, we know that a + b = 20000.

a + b = 20000\implies b = 20000-a \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{5\% of a}}{\left( \cfrac{5}{100} \right)a}\implies 0.05a~\hfill \stackrel{\textit{2\% of b}}{\left( \cfrac{2}{100} \right)a}\implies \begin{array}{llll} 0.02b\\\\ \stackrel{substituting}{0.02(20000-a)} \end{array}

now, we know the total of earned interest is 550 bucks, so then

0.05a~~ + ~~0.02(20000-a)~~ = ~~550\implies 0.05a+400-0.02a=550 \\\\\\ 0.03a+400=550\implies 0.03a=150\implies a=\cfrac{150}{0.03}\implies a=5000 \\\\\\ ~\hspace{24em}\stackrel{20000~~ - ~~5000}{b=15000}
