Answer:
Step-by-step explanation:
Recall that we say that d | a if there exists an integer k for which a = dk. So, let d = gcd(a,b) and let x, y be integers. Let t = ax+by.
We know that 
so there exists integers k,m such that a = kd and b = md. Then,
. Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.
Answer: D. 38x + 1,450 > 4,000
Step-by-step explanation:
It has to be greater than 4,000 so A makes no sense
The parentheses are in the wrong place completely changing the meaning for B
C disregards the info we have about how she's already typed 1,450 words
The answer has to be D
Let the missing % be x.
Now, according to your question ;
5 = x% of 25
5 = x / 100 * 25
thus, 25x = 500
Thus, x = 500/25
= 20
Thus, 5 is 20% of 25.
The only value for x to make tanx = 0 is either 0 or 180 or 0 or pi.
