Answer: B
Step-by-step explanation:
Let's solve the given equation. Then we can see which other equation has the same answer.
-5n+31=-14n-5
36=-9n
n=-4
We need to fina another equation that gives n=4 as the answer.
A. Incorrect
3-6n+3n=-3+4-4n
3-3n=1-4n
n=-2
B. Correct
C. Incorrect
1=0.75n+3.25
-2.25=0.75n
n=-3
D. Incorrect
-1-22n=-20n-9
8=2n
n=4
Answer:
69, -69
Step-by-step explanation:
If the number is positive, the opposite of it is the same number, but negative.
If the number is negative, the opposite of the number is the same number, but positive.
So, -69 would be 69.
69 is the opposite of -69, so the opposite of 69 would go back to -69.

Answer:
two-sixths of 24
Step-by-step explanation:
7<8
We can get the angle with
tan a= opposite side / adjacent side = 35ft/ 50ft=0.7, so a = arctan(0.7)=35°
