45 feet. 4 x 10 =40 then add the other half an inch to get the total of 45 feet or you could say 9 x 5= 45
Answer: k=21
Step-by-step explanation:
1. Distribute the 9 to the k and the -4 in the parentheses.
9 · k = 9k and 9 · -4 = -36
You now have 9k - 36 - 7k. You can combine the like terms of 9k and -7k and get 2k, giving you 2k - 36.
2. For the other side of the equation, you also distribute -2 to the k and -8 in the parantheses.
-2 · k = -2k and -2 · -8 = 16
You now have 32 - 2k + 16. Combine the like terms 32 and 16 (32 + 16) and you get 48. This gives you the equation 48 - 2k.
3. Now you should have the equation 2k - 36 = 48 - 2k.
You want the k on one side of the equation so you need to cancel out one of them. I cancelled out -2k by adding 2k to it. You also need to add this 2k to your 2k on the other side of the equation.
Ex: 2k - 36 = 48 - 2k
+2k +2k
4. Now you should have 4k - 36 = 48. You need to get 4k by itself so cancel out -36 from both sides by adding 36 to -36 and adding 36 to 48.
You should now have 4k = 84 (48 + 36 = 84).
Divide both sides by 4 to get k by itself. 4 divided by 4 makes k and 84 divided by 4 equals 21. This makes k = 21, which is your answer.

Step-by-step explanation:
Answer:
14.2 feet
Step-by-step explanation:
I rounded off to 1 decimal place
The percent off the store should display is 27.0%
- The initial percent off given to Matt = 20%
- The additional percent off given to Matt = 7%
The percent off the store should display is the total percent off given to their product. That is, the addition of the first and second percent off.
The total percent off the store gave to Matt is calculated as;
= 20% + 7%
= 27%
To the nearest tenth of a percent = 27.0%
Thus, the percent off the store should display is 27.0%
