Answer 1

a) 45a+8550:10=9855

45a+855=9855

45a=9855-855

45a=9000

a=9000:45

a=200

b) 100b-213=4785:55

100b-213=87

100b=87+213

100b=300

b=300:100

b=3

c) 9144-6c+(100×25):25=6064

9144-6c+2500:25=6064

9144-6c+100=6064

9244-6c=6064

6c=9244-6064

6c=3180

c=3180:6

c=530

d) 1458+25d-458=10000

1000+25d=10000

25d=10000-1000

25d=9000

d=9000:25

d=360

e) e:15+(1000-17)×5=5482

e:15+983×5=5482

e:15+4915=5482

e:15=5482-4915

e:15=567

e=567×15

e=8505

ordinea descrescătoare: 8505, 530,360,200,3 - Super
