Question

b) (1 873 +b) - 1 256 = 2 765;
c) 9 512 - (3 742 + c) = 2 976;
d) (1 594 +d) - 1210+ 3 300 = 9 000.​

Answer 1

Răspuns:

b) (1873+b)-1256=2765

1873+b=2765+1256

1873+b=4021

b=4021-1873

b=2148

c) 9512-(3742+c)=2976

3742+c=9512-2976

3742+c=6536

c=6536-3742

c=2794

d) (1594+d)-1210+3300=9000

(1594+d)-1210=9000-3300

(1594+d)-1210=5700

1594+d=5700+1210

1594+d=6910

d=6910-1594

d=5316
