Answer:
80 copies
Step-by-step explanation:
4 minutes= 240 seconds. So I did 240 seconds divided by 3 seconds (one copy is made in that time) then you get 80. I don't know if that explanation make sense but the math checks out.
Answer:
x=29
Step-by-step explanation:
180-87=93
93=3x+6
-6 -6
--------------
93=3x
/3 /3
-------------
29=x
x=29
*all angles in a triangle add up to 180. So, 35+52=93. 180-93=87.
C=87
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!
