Question

ajutor repede va rog!!!!

Answer 1

$a,b,c,d-nr.$

$a + b + c + d = 923$

$a = \frac{b}{4}$

$b = 4a$

$a = \frac{c}{2}$

$c = 2a$

$d = a - 13$

$a + 4a + 2a + a - 13 = 923$

$a + 4a + 2a + a = 923 + 13$

$8a = 936$

$a = \frac{936}{8}$

$a = 117$

$b = 4a$

$b = 4 \times 117$

$b = 468$

$c = 2a$

$c = 2 \times 117$

$c = 234$

$d = a - 13$

$d = 117 - 13$

$d = 104$
