Factorise 2-y(7-5y) please
hjlf
Answer:
(y - 1)(5y - 2)

Solution:

Factor:
2 - y(7 - 5y)

Apply the Distributive Property:
2 - 7y + 5y²

Reorder the expression:
5y² - 7y + 2

Rewrite the term:
5y² - 5y - 2y + 2

Regroup terms into two proportional parts:
(5y² - 5y) + ( -2y + 2)

Factor Greatest Common Factors out:
5y(y - 1) - 2(y - 1)
(y - 1)(5y - 2)

In an arithmetic sequence {an}, if a1 = 5 and d = 3, find a72. A) 216 B) 218 C) 221 D) 223
Phoenix [80]

The arithmetic sequence with the given condition is determined recursively by

\begin{cases}a_1=5\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}

So we have

a_2=a_1+3

a_3=a_2+3=a_1+3(2)

a_4=a_3+3=a_1+3(3)

and so on with the general pattern

a_n=a_1+3(n-1)

This means the 72nd term in the sequence is

a_{72}=a_1+3(72-1)=5+3(71)=218

so the answer is B.

There are 17 camels I want to divide 3 person if the first one belongs 1/2 The second one belongs 1/3 and the third one belongs
Sergio039 [100]

Answer:

  1. 9 camels
  2. 6 camels
  3. 2 camels

Step-by-step explanation:

If I add 1 camel to the herd, the first person can get (1/2)×18 = 9 camels.

The second person gets (1/3)×18 = 6 camels.

The third person gets (1/9)×18 = 2 camels.

The total number of camels distributed is 9+6+2 = 17 camels.

The one remaining is returned to me.

  • 1st person: 9 camels
  • 2nd person: 6 camels
  • 3rd person: 2 camels

_____

<em>Comment on the question</em>

This is a trick question, a joke, a riddle. 17 camels cannot be divided in the given proportions without dividing a camel. The total of camels distributed should be 1/2 +1/3 +1/9 = 17/18 of the herd. Each person actually gets 18/17 of their allotment.
