Question

Me restan aún algunos problemas, igual muchas gracias a todos​

Answer 1

Problema 2:

X+15+x+20 +3x +5 +2x+2x+5 =540

9x+45 = 540

9x = 540-45

9x = 495

X = 55

A+ x+15 = 180

A+ 55+ 15= 180

A+ 70 = 180

A= 110

B+x+20 = 180

B + 55+20 = 180

B + 75 = 180

B = 180 - 75

B= 105

C+2x= 180

C+ 55(2)= 180

C + 110= 180

C = 70

D+2x+5= 180

D+ 55(2)+5= 180

D+ 110+5= 180

D+115= 180

D= 65

E+3x+5 = 180

E + 3(55) - 5 = 180

E+ 165 -5 = 180

E + 160 =180

E= 20
