A group of students are intending to offer a present to a friend. If each one pays 3000 LL.

Elanso [62]

Answer:

There are 8 friends and the presents costs $30,000

Step-by-step explanation:

Let x be the number of students and y be the price of the present. Their contributions can be expressed as:

$3000x=y-6000\ \ \ \ \ \ ...i\\\\4000x=y+2000\ \ \ \ \ \ \ \...ii$

#Make y the subject in equation i then substitute in ii:

$y=3000x+6000\\\\\#substitute \ in \ ii\\\\4000x=y+2000\\\\4000x=(3000x+6000)+2000\\\\1000x=8000\\\\x=8\\\\y=3000\times 8+6000\\\\y=30000$

Hence, there are 8 friends and the present is priced at $30,000

pashok25 [27]

Answer:

a = 5r² and b = r²s

Step-by-step explanation:

a3 - b3 = (a - b)(a + ab + b2)

Expressing 125q^6-r^6s^3 as a difference of 2 cubes

125q^6-r^6s^3

= 5³(r²)³ - (r³)²s³

= (5r²)³ - (r²s)³

Comparing with a³ - b³

a = 5r² and b = r²s

Hence the value of a is 5r² and b is r²s
