Make a the subject of the formula: 10a + 9b = 3c

Anuta_ua [19.1K]

Answer:

$a = \frac{3c - 9b }{10}$

Step-by-step explanation:

10a + 9b = 3c

Subtract 9b to isolate the variable a.

10a = 3c - 9b

Now we need a singular a, so divide equation by 10.

$a = \frac{3c - 9b }{10}$

So that's how you do it.

cricket20 [7]

It was 150, went down to 100, so it went 50 bucks.

now, if we take 150 as the 100%, what is 50 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
150&100\\
50&p
\end{array}\implies \cfrac{150}{50}=\cfrac{100}{p}\implies p=\cfrac{50\cdot 100}{150}$
