Question

Ma puate ajuta cineva sa le fac? ​

Answer 1

1.

a+b = 179

a:b = 4 rest 9 => a = 4b+9

4b+9+b = 179

5b = 170

b = 170:5 = 34

a = 145

2.

36+39+75 = 150 (jucarii ramase in magazine)

354-150 = 204 (jucarii vandute in total)

204:3 = 68 (jucarii vandute la fiecare magazin)

I magazin : 68+36 = 104

II magazin : 68+39 = 107

III magazin : 68+75 = 143

3.

a-b = 81

a:b = 4 rest 6 => a = 4b+6

4b+6-b = 81

3b = 75

b = 75:3 = 25

a = 106
