Answer:
24, 48, 72
Step-by-step explanation:
Common Multiples of 8: 8,16,24,32,40,48,56,64,72,80….
Common Multiples of 12: 12,24,36,48,60,72,………..
Hence the First 3 Least common multiple of 8 and 12= 24, 48, 72
second x -1,-3,-5 y 1 3 5 for proportional relation
This is the graph one
A(-1,-4) -->A' (1,-4)
B(-3,-2) ---> B'(3,-2)
C(-1,2) ---> C(1,2)
each book was $16
140-12=128 divided by 8 = 16
hope this helps!
