Is (x + 1) / 2 a monomial （x+1） _________ 2 / 2 (x + 1) is a binomial or a polynomial

Is (x + 1) / 2 a monomial （x+1） _________ 2 / 2 (x + 1) is a binomial or a polynomial

It is a polynomial with "+" in it, and a monomial without "+" - "in it, but it can have" × "/"

Is x = 3 a monomial?

Yes

Determine which of the following formulas are monomials
（1）1×1
（2）5+7
（3）3²
（4）1/2
（5）5/（x+2）

1) 1 × 1 is
(2) 5 + 7 is not
(3) Yes
(4) Half of it is

（1/2 - 5/9 + 5/6 - 7/12）÷（-1/36）

（1/2 - 5/9 + 5/6 - 7/12）÷（-1/36）
=（18/36-20/36+30/36-21/36）×(-36)
=-18+20-30+21
=-7;
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

12.5 * (36-7 and 1 / 5) & 3.6
It's jiansuan. I have the wrong number

12.5 × (36-7 and 1 / 5)? 3.6

(7-6 / 9 + 7-3 / 12 + 1 / 3) × 36

Original formula = (7 / 9-5 / 6 + 7 / 12-10 / 3) × 36
=7 / 9 × 36-6 / 5 × 36 + 7 / 12 × 36-3 / 10 × 36
=28-30+21-120
=-101

One hundred kilogram of apples ate one tenth of the whole on the first day, and the remaining one ninth, one eighth, one seventh, one third and one half on the next eight days. After nine days of eating, how many kilogram remained

100 times (1-1 / 10) times (1-1 / 9) times (1-1 / 8) Multiply by (1-1 / 2) and the answer is 10 kg

How many apples are there in total?

It could be 10 apples

There is a crazy apple, the first day to eat 1 / 9, after seven days to eat 1 / 8, 1 / 7.8 days after the remaining 10, find the original number of apples

10/[(1/2)*(2/3)*(3/4)…… *(8/9)]
=10*9
=90

There is a pile of apples. If there are 10 apples in each bag, there will be 9 apples left. If there are 9 apples in each bag, there will be 8 apples left. If there are 8 apples in each bag, there will be 7 apples left

Let X be a total of X, then x + 1 is a multiple of 10, 9 and 8 at the same time
We can get that x + 1 is a multiple of 360, x + 1 = 360n
X = 360n-1 (n is an integer greater than 0)
As for apple, the total number may be 359 719 1079 and so on``
