Anthony has a part-time job. He decides to save $10 for every $50 that he spends. Final question: If Anthony saved $60, how much money did he earn?

Answers

Answer:

300$

Step-by-step explanation:

If he save 10 for every 50, you just divide. 60/10 = 6. He saved 6 times, if each time he saves he has 50 extra dollars, 6 * 50 = 300 because 6*5 = 30 and there is a extra 0 so 30 and 0 is 300

Let be the integers a,b,c with $a^2-4b=c^2$

To be shown that the number $a^2-2b$ can be written as a sum of 2 perfect squares.

Answers

a^2 - 4b = c^2 <=> a^2 - c^2 = 4b <=> ( a + c )( a - c ) = 4b, cu a, b, c nr. intregi ;
Avem doua posibilitati :
a) a = 2x si b = 2y;
Atunci ( a + c )( a - c ) = 4b <=> x^2 - y^2 = b;
Relatia a^2 -2b devine 2x^2 +2y^2 = ( $√(2) x$ )^2 + ( $√(2) y$ )^2, adica suma a doua patrate perfecte ;

b) a = 2x + 1 si b = 2y + 1 ;
In mod analog. obtii ca x^2 - y^2 + x - y = b;
si, dupa ce prelucrezi, ai ca a^2 - 2b = [ $√(2) ( x + 1 / 2 )$ ]^2 + [] $√(2) ( y + 1 / 2 )$ ^2, adica, suma a doua patrate perfecte .

Bafta!
