Answer:
(21 + 11)2 = 64
So, I don't think teachers do this, but this is my way of doing it
Okay, so first, I divided 64 by 2 :
64 ÷ 2 = 32
Then, I subtracted 11 from 32:
21
Now, to check, just do the problem :
(21 + 11)2 = 64
32 * 2 = 64
Hello! To solve this problem, we have to do 6 / 3/4 (6/0.75). You do this, because you’re using 6 yards of fabric and you use 3/4 yards of fabric per pillow. If you know it, use the rule Keep, Change, Flip. Keep 6/1 the same. Change the division symbol into a multiplication symbol. Flip 3/4 over into 4/3. 6/1 * 4/3 = 24/3 or 8 when simplified. Penny can make 8 pillows using 6 yards of fabric.
Answer:
525
If you want exactly one ace, then your answer is correct. (525) is the number of 5-card hands in the deck, and you have 4 choices for which ace to include (hence, (41)), and 48 choose 4 choices for the other 4 cards (hence, (484)).
Well put them in equal groups multiply them and boom u answer
Because 45 is half of 90, 5x=90. 5 times 18 is 90 so x is 18.
