Answer:

c x = 10/3

Step-by-step explanation:

log (3x) =1

Take each side to 10 to the power. That will get rid of the base 10 log

10 ^(log (3x)) =10^1

3x = 10

Divide by 3

3x/3 = 10/3

x = 10/3

Answer:

d = $\frac{1}{4}$

Step-by-step explanation:

Given

= 16(d + 1) = - 20 ← distribute parenthesis on left side

- 16d - 16 = - 20 ( add 16 to both sides )

- 16d = - 4 ( divide both sides by - 16 )

d = $\frac{-4}{-16}$ = $\frac{1}{4}$

Each marble bag sold by Hans's Marble Company contains 8 purple marbles for every 5 green marbles. If a bag has 30 green marbles

gregori [183]

We can set up a proportion since we know the ratio between the # of purple marbles and the # of green marbles.

A ratio is a way to compare two different values: for every 8 purple marbles there are 5 green marbles

<h2> $\frac{8}{5} = \frac{p}{30}$ </h2><h2 /><h2>when we cross multiply, we get 5p = 240 </h2><h2>we divide both sides by 5 to isolate the variable </h2><h2 /><h3><u>There are 48 purple marbles </u></h3>

Divide 7/24 by 35/48 and reduce the quotient to the lowest fraction

tiny-mole [99]

$\frac{7}{24}$ ÷ $\frac{35}{48}$
Multiply $\frac{7}{24}$ by the reciprocal of $\frac{35}{48}$ , which is $\frac{48}{35}$

= $\frac{7}{24}$ × $\frac{48}{35}$
= $\frac{336}{840}$

We can simplify it further:
The greatest common factor here is 168
$\frac{336/168}{840/168}$

= $\frac{2}{5}$
