Answer:
Explanation:
1) 4 + 7 = 11
It should be multiple of 11.
So it is 33
2) Sam and Bethan's share = 5x + 4x = 9x
9x = 54
x = 54/9 = 6
Sam's share = 5x = 5*6 = 30
Bethan's share = 4x = 4*6 = 24
3) 2x +3x +7x = 90
12x = 90
x = 90/12 = 7.5
Weight of small bag = 2x = 2*7.5 = 15
Weight of Medium bag = 3x = 3*7.5 =22.5
Weight of large bag = 7s = 7 * 7.5 = 52.5
4) Let the angles be 7x, 18x , 12x
7x = 35
x = 35 /7 = 5
A = 7x = 7*5 = 35
B = 18x = 18*5 = 90
c = 12x = 12*5 = 60
5)a) 14:56 = 1/4 {giving by 14th table}
b)Online:shop sales = 180:60 = 18: 6 = 3:1
