Question

Help me pls i know is just 10 but plssssssssssssssssssssssssss

Answer 1

Step-by-step explanation:

4:7

12:21

12 +21 =33, between 24 to 40

Thus, theres 33 students in class

5:4

5+4=9

54÷9=6

6×5=30

6×4=24

Thus Sam gets £30 while Bethan gets £24

Answer 2

Answer:

Step-by-step 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
