Use Dalton's law. Answer is:

#p_(Xe)=462.71# #mmHg#

Dalton's law states that:

#p_i/(Σp_i)=n_i/(Σn_i)#

where #p_i# is the pressure and #n_i# are the moles of each individual gas and #Σ# is the notation of their sum #(Σx_i=x_1+x_2+...)#.

#Σp_i=1560# #mmHg#

#Σn_i=1.5+2.65+1.75=5.9# #mol#

By using Dalton's law on #Xe#:

#p_(Xe)/(Σp_i)=n_(Xe)/(Σn_i)#

#p_(Xe)=n_(Xe)/(Σn_i)*Σp_i=1.75/5.9*1560# #cancel(mol)/cancel(mol)*mmHg#

#p_(Xe)=462.71# #mmHg#
