$=\tt \frac{3}{7} m - 3 + 4n + \frac{2}{7} m - 2n + 6$

$=\tt \frac{3}{7} m + \frac{2}{7} m + 4n - 2n + 6 - 3$

$\color{plum} =\tt \frac{5}{7}m + 2n + 3$

○=> Therefore,

$\color{hotpink}\tt \frac{3}{7} m - 3 + 4n + \frac{2}{7} m - 2n + 6 \color{plum}= \frac{5}{7} m + 2n + 3$

What is the value of AAA when we rewrite \left(\dfrac {6}{17}\right)^{9x}( 17 6 ) 9x (, start fraction, 6, divided by, 17, end

sineoko [7]

We have been given an expression $\left(\dfrac {6}{17}\right)^{9x}$ . We are asked to find the value of A when rewrite our given expression as $A^{x}$ .

To solve our given problem, we will use exponent properties.

Using exponent property $a^{mn}=(a^m)^n$ , we can rewrite our given expression as:

$\left(\dfrac {6}{17}\right)^{9x}=\left(\left(\dfrac {6}{17}\right)^9\right)^{x}$

Now, we will compare our expression with $A^{x}$ .

Upon comparing $\left(\left(\dfrac {6}{17}\right)^9\right)^{x}$ with $A^{x}$ , we can see that $A=\left(\dfrac {6}{17}\right)^9$ .

Therefore, the value of A is $\left(\dfrac {6}{17}\right)^9$ .

We can further simplify $\left(\dfrac {6}{17}\right)^9$ as:

$\left(\dfrac {6}{17}\right)^9=\frac {6^9}{17^9}=\frac{10077696}{118587876497}$

Mr. Santiago can buy light fixtures in packages of 12 and light bulbs in packages of 9. He bought the fewest number of light fix

liq [111]

Answer:

3 and 4 packages

Step-by-step explanation:

We need to find the LCM of 12 and 9.

9 = 3*3
12 = 2*2*3

<u>Their LCM is:</u>

LCM(12, 9) = 2*2*3*3 = 36

Number of light fixtures and light bulbs is 36.

<u>Number of packages will be:</u>

36/12 = 3 and
36/9 = 4 respectively.

Heidi has an average score of 78 for her first six chemistry tests. If Heidi"s scores for the first four tests were 82,78,87, an

elixir [45]

Answer:

(A)74

Explanation:

Let her average score on the last two tests = x.

The six scores will now be: 82,78,87,73, x and x.

Since the average score for her first six chemistry tests = 78

$\frac{82+78+87+73+x+x}{6}=78$

We then solve for x.

$\begin{gathered} 320+2x=78\times6 \\ 320+2x=468 \\ 2x=468-320 \\ 2x=148 \\ x=\frac{148}{2} \\ x=74 \end{gathered}$

Her average score for the last two tests is 74.
