He can because you can add it mentally. You can just have 23 in your head and count by adding 10 "4" times.
Hope this helped☺☺
The data observed from the triangle are given below.
Statement Reason
Given
Draw 
so that M is the midpoint of QR. Two points determine a line
Definition of midpoint
Reflexive property of congruence
SSS congruence postulate
CPCTC
SSS means side-side-side
CPCTC means corresponding parts of the congruence triangle are congruent.
Hence the given triangle is SSS congruence postulate

Answer:
1000 represents the amount of trash that was originally present in the landfill before dumping any extra trash.
i.e : It is the amount of trash at day zero
Explanation:
The initial value of a function is defined as the started value of the function independent of any variables present in the function
The given function is:
n = 2000x + 1000
where n is the amount of trash and x is the number of days
To get the initial value, we will set the variable (x) to be equal to zero
Therefore, initially:
n = 2000(0) + 1000 = 1000
This means that the initial value of the trash at day zero is 1000.
Hope this helps :)
