Question

calculeaza: a×d-a×b, daca: a-5×5×4=b×10=c:2=600:d=10×2×5
vă rog mult urgent

Answer 1

a-5×5×4=b×10=c:2:2=600:d=10×2×5
Ultima operație
600:d=100
d=600: 100 d=6

c:2:2 = 600:6
c:2:2=100
c= 100×2×2 c=400

b×10=400:2:2
b×10=100 b=10
b=100:10

a-5×5×4=10×10
a-100=100
a=100+100 a=200

Calculeaza: c×d-a×b
400×6-200×10
2400-2000
=400
