Please do this for me <br><br> I am very lazy

Alexandra [31]

First, let's turn all the numbers into improper fractions so that we can find the answer easier.

-2 $\frac{1}{4}$ = r - $\frac{4}{5}$

- $\frac{9}{4}$ = r - $\frac{4}{5}$

Now we have to isolate 'r'.

First, we have to make sure that the variable is on one side and all the numbers are on the other side.

To do this, we have to add $\frac{4}{5}$ to both sides.

In order to do this, we need to ensure that both fractions have a common denominator.

- $\frac{9}{4}$ = r - $\frac{4}{5}$

Ensure that the denominators are the same:

$\frac{45}{20}$ = r - $\frac{16}{20}$

$\frac{45}{20}$ + $\frac{16}{20}$ = r

$\frac{61}{20}$ = r

Good luck!

Condense the log equation: 4 log x + log y - 5 log z

Setler [38]

Answer:

The condensed log equation is: $\log{\frac{x^4y}{z^5}}$

Step-by-step explanation:

We use these following logarithm properties to solve this question:

$a\log{x} = \log{x^a}$

$\log{a} + \log{b} = \log{ab}$

$\log{a} - \log{b} = \log{\frac{a}{b}}$

In this question:

$4\log{x} = \log{x^4}$

$5\log{5} = \log{z^5}$

$4\log{x} + \log{y} - 5\log{z}$

Becomes:

$\log{x^4} + \log{y} - \log{z^5}$

Now applying the addition and subtraction properties, we have:

$\log{\frac{x^4y}{z^5}}$

The condensed log equation is: $\log{\frac{x^4y}{z^5}}$

What is the answer to 3/4 +1/3

Elis [28]

Well, to add fractions, you need to find a common denominator. In this case, the smallest common denominator would be 12. So you must multiply each fraction so that both denominators are 12.
3/4*3/3=9/12
1/3*4/4=4/12
Add those two fractions together, reduce if possible, and you have your answer!
9/12+4/12=13/12
You can't reduce, so 13/12 is your answer.
Hope it helps!
