Me ajudem na moralzinha kk❤️

Answer 1

Resposta:

3)

a) 10x = 25 - 5

10x = 20

x = 20/10

x = 2

b)  55=5y+30

55-30 = 5y

25=5y

y =25/5

y = 5

c) 40 = 22 + 2t

40-22=2t

18=2t

t = 18/2

t = 9

4) Multiplica Cruzado

a) x /5 = 20/1

x = 100

b) 2v=70

v = 70/2

v = 35

c) 10p=30

p = 30/10

p = 3
