Step-by-step explanation:

part A:12+7x

first day 12+7=$19

second day 19+7=$26

third day 26+7=$33

....

so

number of moneys on x day will be

12+7*x where x represent the number of days

so

for three days

12+7*3=12+21=33

part B:138

12+7x where x=18

12+7*18=12+126=$138

He will have $138 on the 18th day.

Blank 4: Transitive property of convergence

Blank 5: Definition of Bisect

Step-by-step explanation:

We need to fill in the blanks from the given options.

Blank 1:

ABCD is a parallelogram

This is given

So, blank 1: Given

Blank 2:

A parallelogram have parallel sides i.e in the given parallelogram AD is parallel to BC and AB is parallel to DC

So, Blank 2 : AD is parallel to BC

Blank 3:

We are given <3≅<2

So, Blank 3: <3≅<2

Blank 4:

We know, <1≅<3 and <3≅<2 using transitive property (A≅B and B≅C then A≅C)

So, <1 ≅ <2 is due to transitive property of convergence

Blank 4: Transitive property of convergence

Blank 5:

DC bisects <ADE

A bisect is an line or angle that divides into exactly two parts.
