The value of the digit 5 in the ten millions place would be 50,000,000, where the digit 5 in the hundreds place would be 500. Therefore, that would be 5x as much. (I was having a hard time understanding, please reply and make it more clear, thanks and have a good day! =D)
Answer:
56
Step-by-step explanation:
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:
Explanation:
Identity: sec2θ=1+tan2θ
sec2(π2−x)−1=1+tan2(π2−x)−1
=tan2(π2−x)
Identity: tan(π2−θ)=cotθ
=cot2x
C. 51* I am pretty sure is it
