Question

Упрости выражения. Потом подставь значения букв и вычисли.

Answer 1

b+5b+6b = 12b =12*300 = 3600
d+d+d+d = 4d = 800*4 =1200
9p+20p+8p = 37p = 37*80=2960
b+b+b = 3b = 3*300=900
14p+20p+p = 35p = 35*80=2800
10a+3a+2a = 15a = 15*30=450
c+c+2c = 4c = 4*50=200
4s+3s+7s = 14s = 14*20=280
t+2t+5t+t = 9t = 9*90=810
