Answer:
Step-by-step explanation:
a) 2x = 10
Divide both side by 2
x = 10/2
x = 5
b) -3x = 21
Divide both sides by (-3)
x = 21/(-3)
x = -7
![c) \frac{1}{3}x = 6](https://tex.z-dn.net/?f=c%29%20%5Cfrac%7B1%7D%7B3%7Dx%20%3D%206)
Multiply both sides by 3
x = 6*3
x = 18
![d)\frac{-1}{2}x = -7](https://tex.z-dn.net/?f=d%29%5Cfrac%7B-1%7D%7B2%7Dx%20%3D%20-7)
Multiply both sides by (-2)
x = -7 * (-2)
x = 14
B is the correct option
ditribute first on the right side
then add 8 to the right side and that will make y by itself
The interquartile range of the data set is 18, hope this helps :)
Z score = (x-μ)/σ
2 = (x-50) / 10; solve for x
20= x-50 and x = 70 : TRUE
