Amanda [17]

Lou Ann needed 25 packages that contains all the 150 invitations.

Lou Ann needed to mail 150 invitations to her school play. The invitations came 6 to a package.

<h3>What is Statistic?</h3>

The statistic is the study of mathematics which deal with relations between comprehensive data.

Here, 1 package contains 6 invitation
so 1 package = 6 invitations
total invitation= 150 invitations
now number of packages = Total invitation/ 6 invitation = 150/6
=25

Thus the required number of packages is 25.

__ __ Calcula (a+b), si la suma de los complementos aritmeticos de ab y ba es 24
IceJOKER [234]

Respuesta:

dieciséis

Explicación paso a paso:

100-ab - - - - (1)

100-ba - - - - (2)

Sumando (1) y (2) sumas hasta 24

100-ab + 100-ba = 24

100 + 100 - ab - ba = 24

200- (10a + b) - (10b + a) = 24

200-10a-b-10b-a = 24

200-24 = 10a + 10b + b + a

176 = 11a + 11b

176 = 11 (a + b)

176/11 = a + b

16 = (a + b)
