Statistics is not an exact science, meaning that with any answer, there will be variance. This is because the sample size used to obtain values is always smaller than the population being studied.
Answer:
Step-by-step explanation:
Solving For V.
2v=−10x
You need to divided both sides by 2.
2v
/2 = −10x
/2
v = −5x
Answer:
v = −5x
This would be the identity property of addition telling us that any number added to zero is that number (i.e. 6 added to zero is still 6)
Step-by-step explanation:
7x+5y=25 ×3 7×-1.5+5y=25
5x+3y= -23 ×5 -10.5 +5y =25
5y= 25 + 10.5
21x+15y=75 5y= 35.5
25x+15y=69 y= 7.1
-4x=6
x=-1.5
