Answer:

A) 11/36

Step-by-step explanation:

x + 4/9 = 3/4

get a common denominator of 36 (4*9 = 36)

x + 4/9 * 4/4 = 3/4 * 9/9

x + 16/36 = 27/36

subtract 16/36 from each side

x + 16/36 - 16/36 = 27/36 -16/36

x = (27-16)/36

x = 11/ 36

Hi There!

Step-by-step explanation:

Find Common Denominators:

4/9 = 16/36

3/4 = 27/36

Subtract:

27/36 - 16/36 = 11/36

Check:

11/36 + 16/36 = 27/36

Answer:

A) 11/36

Hope This Helps :)

Answer: Choice A. 4 times

========================================================

Explanation:

We'll be using this formula

$m = \frac{f(b)-f(a)}{b-a}$

to compute the average rate of change (AROC) from x = a to x = b. Note how this is effectively the slope formula because y = f(x).

To start things off, we'll compute the AROC from x = 1 to x = 2.

$m = \frac{g(b)-g(a)}{b-a}\\\\m = \frac{g(2)-g(1)}{2-1}\\\\m = \frac{5(2)^2-5(2)^1}{2-1}\\\\m = \frac{10}{1}\\\\m = 10\\\\$

Do the same for the AROC from x = 3 to x = 4.

$m = \frac{g(b)-g(a)}{b-a}\\\\m = \frac{g(4)-g(3)}{4-3}\\\\m = \frac{5(2)^4-5(2)^3}{4-3}\\\\m = \frac{40}{1}\\\\m = 40\\\\$

The jump from m = 10 to m = 40 is "times 4", which is why choice A is the final answer.

For number one you have to do 45.6 Divided by 2.54 to get your answer and your answer is going to be 17.95 but The answer actually continues but but sometimes there’s going to be a lot of numbers and people don’t wanna write it down so they’re just gonna cut it short I hope that kind of helped
