la diferencia entre 50 y -60
atudaaaaaaaaaaaaaaaaa

Answer 1

Respuesta:

L= 3a a = ancho l= largo

P=40

P = largo + ancho L= 3a

40 = 3a + a L= 3 (10)

40 = 4a L= 30

40/4 = a

10 = a

a= 10

2. x + y = 182 (1)

x - y = 60 (2)

(2) x- y = 60 x = 60 + y

x = 60 + y x = 60 + 61

(1) (60 + y) + y = 182 x = 121

60 + 2y = 182

2y = 182 - 60

2y = 122

y = 122/2

y = 61

3. x = num mayor y = num menor

x - y = 6 (1)

2y + x = 54 (2)

(1) x = 6 + y x= 6 + y

(2) 2y + ( 6+ y) = 54 x = 6 + 16

3y + 6 =54 x = 22

3y = 54-6

3y = 48

y= 48/ 3

y= 16

GAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
