2(4z-9-11)=166-46
8z-18-22=120
8z-40=120
Add 40 from both side
8z-40+40=120+40
8z=160
Divided 8 from both side
8z/8=160/8
z=20. Hope it help!
Answer:
117
Step-by-step explanation:
8/12. 4/6. 2/3 is the simplest. Just keep dividing it down until you can't divide anymore:)
First you have to take the whole number (43) and then take the decimal and put it over 100 (77/100).
0.71 x 22 is the expression that works, because 1 AUD = 0.71USD.
