Simplify the following:
(k^3 k^7)/3 - 5
Combine powers. (k^3 k^7)/3 = k^(7 + 3)/3:
k^(7 + 3)/3 - 5
7 + 3 = 10:
k^10/3 - 5
Put each term in k^10/3 - 5 over the common denominator 3: k^10/3 - 5 = k^10/3 - 15/3:
k^10/3 - 15/3
k^10/3 - 15/3 = (k^10 - 15)/3:
Answer: (k^10 - 15)/3
X/7 + 10
X represents the unknown number that is being divided by 7. Then you just add 10 to that

The 2 tringles are ten equal ASA
Answer: Ricki's route to school is 19/20 miles long.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Sidewalk: 7/10 miles
</em>
- <em>Shortcut: 1/4 miles
</em>
So, to calculate the length of Ricki's route to school we have to simply add both lengths. (Sidewalk and shortcut)
Mathematically speaking:
7/10 + 1/4 = 14/20+ 5/20 = 19/20 miles
Ricki's route to school is 19/20 miles long.
