Q=20
1. 10q-89
2. (125-q):7
3. (11q:4) +25
4. (14q+80) :30

Answer 1

1. 10 (20) - 89 = 200 - 89 = 111
2. (125 - 20) : 7 = 105 : 7 = 15
3. (11 (20) : 4 ) + 25 = (220 : 4) + 25 = 55 + 25 = 80
4. (14 (20) + 80) : 30 = (280 + 80) : 30 = 360 : 30 = 12

Answer 2

Q =20
1. 10q - 89 =10.20 - 89 = 111
2.(125 - q ):7 = (125 - 20):7 = 15
3.(11q:4)+25 = (11.20 : 4)+25 = 80
4.(14Q+80):30 = (14.20+80):30 = 12
