Let a=3/4 and b=1/5. If a*x=b, then what is x?

Anarel [89]

In general, any equation like $ax=b$ (assuming $a \neq 0$ ) is solved by

$x= \dfrac{b}{a}$

So, in your case, the solution is

$x = \dfrac{\frac{1}{5}}{\frac{3}{4}}$

Dividing by a fraction means to multiply by the inverse of that fraction:

$\dfrac{\frac{1}{5}}{\frac{3}{4}} = \dfrac{1}{5} \cdot \dfrac{4}{3} = \dfrac{4}{15}$

Lucas invested money in two accounts: one paying 3% interest and the other paying 5% interest. He invested $100 more in the 5% a

Anni [7]

He invested "a" at 3% and "b" at 5%

now, he invested 100 more in "b", so, whatever "a" may be, b = a + 100

now, how much is the interest yield of each? well
how much is 3% of a? well, (3/100) * a, or 0.03a
and 5% of b? well (5/100) * b, or 0.05b

now, we know the total yield was 53 bucks, thus 0.03a + 0.05b = 53

thus $\bf \begin{cases}
\boxed{b}=a+100\\
0.03a+0.05b=53\\
----------\\
0.03a+0.05\left( \boxed{a+100} \right)=53
\end{cases}$

solve for "a", to see how much was invested at 3%

what about "b"? well, b = a + 100

Write expression as the logarithm of a single number<br> log6 + log8 - log2

Dafna1 [17]

<h2>log (6 ) + log ( 8 ) − log ( 2 ) </h2><h2 /><h2> Answer:</h2>

Exact Form: ㏒ ( 24 )

Decimal Form: 1.38021124

<h2>Explanation:</h2><h3> Use the product property of logarithms, </h3>

㏒b ( x) + ㏒b ( y ) = ㏒b ( x y ).

㏒ ( 6 ⋅ 8 ) − ㏒ ( 2 ) .

<h3> ⇒Use the quotient property of logarithms,</h3>

㏒ b ( x ) − ㏒ b ( y ) = ㏒ b ( x y ) .

㏒ ( 6 ⋅ 8/ 2 )

<h3> ⇒Reduce the expression by cancelling the common factors. </h3>

Factor 2 out of 6 ⋅8 .

log ( 2 ( 3 ⋅ 8 ) / 2 )

<h3> Divide 3 ⋅ 8 by 1 .</h3>

㏒ ( 3 ⋅ 8 )

Multiply 3 by 8 .

㏒ ( 24 )

<h3>The result can be shown in both exact and decimal forms. </h3><h3> Exact Form: ㏒ ( 24 ) </h3><h3> Decimal Form: 1.38021124</h3>
