me ajudem,com cálculos por favor​

Answer 1

Resposta:

a: 59

b:67,70

c:44

d:68

e:20

f:59

Explicação passo-a-passo:

a: 73+48=121

180-121=59

b:90+22,30=112,30

180-112,30=67,70

c: 3x+40+x+10+x-10=180

5x=180+40-10+10

5x=220

x=220/5

x=44

d:180-116=64

64+x+x-20=180

2x=180+20-64

2x=136

x=136/2

x=68

e:40+20=60

180-60=120

3x+120=180

3x=180-120

3x=60

x=60/3

x=20

f:180-121=59

62+59+x=180

x=180-62-59

x=59
