western beach:  y = -2x + 100

dunes beach : y = 5x + 20

set the equations equal to each other

-2x + 100 = 5x + 20

100 - 20 = 7x

80 = 7x

80/7 = x

x ~ 11.43 years

Step-by-step explanation:

The  mass  of Aluminium if  the volume  is 8.5 cm³  is 22.95 grams

      calculation

 mass  =  density   x volume

 The density of Al is=2.7  g/cm³  (from given table)

 volume = 8.5 cm³

mass  is therefore = 2.7 g/cm³  x 8.5 cm³   =22.95 grams
