Explain why 2n+1 must be an odd number
Lorico [155]
If is an integer (a whole number), then the expression represents an even number, because even numbers are the multiples of 2. The expressions 2 n − 1 and 2 n + 1 can represent odd numbers, as an odd number is one less, or one more than an even number.

Omar has 2-5/8 cups of dough to make dumplings. If he uses 3/16 cup of dough for each dumpling, how many whole dumplings can Oma
Arte-miy333 [17]

Answer:

The number of whole dumpling does Omar make is 14 .

Step-by-step explanation:

Given as :

The number of cups does Omar has to make dumplings = x = 2\dfrac{5}{8}

i.e x = \dfrac{16 + 5}{8}

or, x =  \dfrac{21}{8}

Again

The number of cups uses for each dumpling = y =  \dfrac{3}{16}

i.e y = \dfrac{3}{16}

Let The number of whole dumpling does Omar make = z

So,  number of whole dumpling does Omar make = \dfrac{\textrm number of cups does Omar has to make dumplings}{number of cups uses for each dumpling }

Or, z = \dfrac{x}{y}

Or, z = \frac{\frac{21}{8}}{\frac{3}{16}}

Or, z = \frac{21\times 16}{8\times 3}

∴  z = 7 × 2

i.e z = 14

So, The number of whole dumpling does Omar make = z = 14

Hence, The number of whole dumpling does Omar make is 14 . Answer
