Answer:
220
Step-by-step explanation:
If we take 20 common (as in we can take it out and group the rest) , we can say 20 (15 7/9-4 7/9) which is equal to 20 (11). 20x11 = 220.
V=480cm³ . 10 and 12
9 cows and 25 chicken
First two lines
w + k = 34 1
4w + 2k = 86 2
5a+8+(-2a)=-7
5a+8-2a=-7
5a-2a=-7-8
3a=-15
3a/3=-15/3
a=-5
The answer is B
My friend says 5 is 60 and 6 is b.
