Answer:
x = 0
Step-by-step explanation:
The zero is the value of x that makes the linear factor zero:
5x +0 = 0
5x = 0 . . . . . simplify
x = 0/5 = 0 . . . . divide by 5
The associated zero is x = 0.
B because it makes the most sense to me
Given:
1 set requires 4 couples 8 dancers.
Total number of people at a square dance = 250.
To find:
The greatest number of sets possible at the dance.
Solution:
We have,
Total people = 250
1 set = 8 people.
![\text{Number of possible sets}=\dfrac{\text{Total people}}{\text{People required for 1 set}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20possible%20sets%7D%3D%5Cdfrac%7B%5Ctext%7BTotal%20people%7D%7D%7B%5Ctext%7BPeople%20required%20for%201%20set%7D%7D)
![\text{Number of possible sets}=\dfrac{250}{8}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20possible%20sets%7D%3D%5Cdfrac%7B250%7D%7B8%7D)
![\text{Number of possible sets}=31.25](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20possible%20sets%7D%3D31.25)
Number of possible sets cannot be a decimal or fraction value. So, approx. the value to the preceding integer.
![\text{Number of possible sets}\approx 31](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20possible%20sets%7D%5Capprox%2031)
Therefore, the number of possible sets at the dance is 31.
The footage is 1000 square footage
3x + 2y - 4z/x for x=5, y=-2, z=10
3x + 2y - 4z/x
3(5) + 2(-2) - 4(10)/(5)
15 - 4 - 40/5
15 - 4 - 8
11 - 8
