Expression: <span>a = 9b²c

b</span>² = a/9c

b = √(a/9c)

b = √a/3√c
Or b = 1/3 √(a/c)

In short, Your Answer would be: Option D

Hope this helps!

<h2>Answer:</h2>

The Slope is $\frac{1}{4}\\$

<h2>Explanation:</h2>

Notice that both the points, $(-7,-6)$ and $(-3,-5)$ , are on the line. So we can use those points to calculate the slope. Recall that that slope of the line $m$ can be calculated by $\frac{y_2 -y_1}{x_2 -x_1}\\$ if we have the points, $(x_1,y_1)$ and $(x_2,y_2)$ .

<h3>Calculating for the slope of the line:</h3>

Given

$(-7,-6)$

$(-3,-5)$

$m = \frac{-5 -(-6)}{-3 -(-7)} \\ m = \frac{-5 +6}{-3 +7} \\ m = \frac{1}{4}$

Can you solve: 6/5=n+2/2n-3

OverLord2011 [107]

solving $\frac{6}{5}=\frac{n+2}{2n-3}$ we get value of n: $n=4$

Step-by-step explanation:

Solving the expression:

$\frac{6}{5}=\frac{n+2}{2n-3}$

Solving:

$\frac{6}{5}=\frac{n+2}{2n-3}\\Cross\,\,multiply:\\6(2n-3)=5(n+2)\\Simplifying:\\12n-18=5n+10\\Combining\,\,like\,\,terms:\\12n-5n=10+18\\7n=28\\n=\frac{28}{7}\\n=4$

So, solving $\frac{6}{5}=\frac{n+2}{2n-3}$ we get value of n: $n=4$

Can you simplify these please thank you

kap26 [50]

-4(9-3)/(8-2) = -4

(8^2-2^5)/(24/6)+3^2= 17

5(16-5)-1/(4^2-7) = 6

Hope this helps! Please rate if I helped you! Any questions please just ask! Thanks!!
