Answer:

Step-by-step explanation:

1. 27 - 3 (because 3 are left over) = 24. Then, 24 ÷ 6 = 4 children.
2. If Mina has £7.20, that means she has 720 pence. If half is given to her brother, then she has £3.60 left. (720 ÷ 2 = 360 pence, which is £3.60)
3. 17 × 10 = 170
2 × 20 = 40
170 + 40 = 210, which is £2.10
7 - 5^2 x 3 - 4^3 = 7 - 25 x 3 - 64 = 7 - 75 - 64 = -132
Answer:
C
Step-by-step explanation:
In a proportional relationship the constant of proportionality k is
k = 
Check this ratio for each of the values
A
= 1.5 ,
= 1.5 ,
= 1.4347.... ← Thus not A
B
= 1.1875 ← Thus not B
C
= 1.5 ,
= 1.5 ,
= 1.5
Thus the table with k = 1.5 is Table C
