So hmmm 7, 0, -7.... what the dickens is going on? hmmm is really dropping each time by 7, so, 7-7, 0, and 0-7, -7 and so on.
so, the "common difference" is then -7, and our first term is 7, now, who's -175? let's check.
If the tens digit increases by one and the ones digit remains the same
Step-by-step explanation:
6m + 3z + 4m + 2w - 5z
6m + 4m + 3z - 5z + 2w
10m - 2z + 2w
Therefore the answer is 10m -2z + 2w
Hello!
For this you have to find the amount of every color of beads.
300 * 0.30 which is 90 black beads
300 * 0.25 is 75 red beads
300 * 0.15 is 45 white beads
Then you add them.
90+75+45 = 210
Then subtract them from the total
300 - 210 = 90
The answer is 90 blue beads or 30%
Hope this helps!
