Question

Si: A = 4 (15 - 12,5) + (12,5 + 7,5)
B = 100 - 6 (20 - 14,8)
Halla: 2A + B - 10,078
Porfa ayudenme

Answer 1

a = 30
b = 68.8

2A + B - 10,078
2(30) + 68.8 - 10,078 = -9949.2

Answer 2

a= 4*15 - 4*12,5 + 20
a= 60-50+20
a= 30
b=100-(6*20 - 6*14,8)
b=100-(120-88,8)
b=100-31,2
b=68,8

2a+b-10,078
2*30+68,8-10,078
60+58,722
118,722
