Answer:
Step-by-step explanation:
Given equation:
Solving for unknown variable 
Adding 8 both sides by additive property of equality.
Squaring both sides to remove the square root.
Adding 5 both sides by additive property of equality.
Dividing both sides by 6 to isolate
∴
6.8,6.827,6.86,6.9
1.2,1.203,12.03, 12.301,12.31
Answer:
The second one is correct.
Answer:
the answer is n=2
Step-by-step explanation:
so put the problem like this 3/5n - 4/5 = 1/5n
In order to get the answer u have to subtract 3/5n to both sides which makes the problem -4/5 = -2/5n and when u divide -4/5 by -2/5 it equals 2
-4/9 times -5/8 you can cross cancel the 4 and 8 so it makes the problem -1/9 times -5/2 which equals -5/18
