Answer:
x+y= 59, x-y= -13
Step-by-step explanation:
We know that x is the smaller number and y is the bigger number. We also know that the difference is 13, meaning x-y= -13. Since the sum of the two numbers is 59, x+y= 59
Hey,
The lower quartile is the median of the lower half of the data set.
The median is the middle most number or the average of the two middle most numbers depending on how many values there are.
Cheers,

Answer:
D and E
Step-by-step explanation:
Using the rule of radicals
⇔ ![\sqrt[n]{a^{m} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D)
Given
= (![\sqrt[7]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7B3%7D)
)^4 → D or
= ![\sqrt[7]{3^{4} }](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7B3%5E%7B4%7D%20%7D)
= ![\sqrt[7]{81}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7B81%7D)
→ E
k/9-1=12
We move all terms to the left:
k/9-1-(12)=0
We add all the numbers together, and all the variables
k/9-13=0
We multiply all the terms by the denominator
k-13*9=0
We add all the numbers together, and all the variables
k-117=0
We move all terms containing k to the left, all other terms to the right
k=117
