Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Find the solutions to the linear equations represented by the models shown, where circles and squares are shown evenly balanced on balance
beams. Assume the welght of a circle is 1 unit and the weight of a square is x units,
x = 9
x=2
x = 6
x=5
X= 4
x=3

Step-by-step explanation:

Match the circles on the left with circles on the right. Divide any remaining circles evenly between the remaining squares. See below for one way to do this.

b) well because you get well

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
