Question

a) x + 3 = 12 b) m – 7 = 20 c) 5. p = 25 d) b : 3 = 4 e) 4 + f = 4 f) 17 -h = 9 g) z : 4 = 1 h) 30 : n = 6

Answer 1

respuesta:

a) x + 3 = 12

x = 12 - 3

x =9

b) m -7 = 20

x= 20 +7

x =27

c)5.p =25

p=25/5

p=5

d)b:3=4

b=4.3

b=12

e)4+f=4

4-4=f

0=f

f)17 - h =9

17 + 9 = f

26= f

g)z :4 = 1

z = 4.1

z =4

y)30:n=6

n=6.30

n=180
