The recursive rule is

.
The iterative rule is

The recursive rule is given by the formula

, where d is the common difference. Our common difference is -4, which gives us the recursive rule above.
The iterative rule begins with the formula

, where a₁ is the first term and d is the common difference. Our first term is 10 and our common difference is -4:
<h2>Answer:</h2><h2 /><h2>The unit rate is 75/1.</h2><h2 /><h2>Step-by-step explanation:</h2><h2 /><h2>To figure out this problem you have to divide. </h2><h2>375 divided by 5 is equal to 75. </h2><h2 /><h2>Therefore the unit rate is 75/1.</h2><h2 /><h2>Hope this helps and have a great day!!!</h2><h2 /><h2>:)</h2>
Answer:
The width of the actual pool is 12 meters
Step-by-step explanation:
You can put Kiara's scale into a ratio or fraction to help visualize it better: 13/6. Now, let's put what we do know for the other ratio into a fraction. we know that the pool is 26 centimeters wide, and since the 26 matches with the 13, that goes in the numerater. since we don't know the denominator, we can just put 26/x (you can use whatever letter you like but I'll use x here)
So in order to get 13/6 to 26/x, we need to find how to figure out what we are doing to the original fraction. Since 13 x 2= 26, it looks like we are multiplying the ratios by 2. Now that we know that, we can multiply the denominator (6) by 2 to equal 12, our answer.
Hope this helps :)
