<u>The postal service delivered:</u>
7.14 × 1010 pieces of mail in December
3.21 × 1010 pieces of mail in January
Total number of mail delivered is;
(7.14 + 3.21) × 1010
= 10.35 × 1010
= 1.035 × 10100 (in one decimal point form)

Step-by-step explanation:
Combine 1
/2
and x
.
y
=
x
/2
−

x
−
y
=
−
16
Replace all occurrences of y in 2

.
y
=
x
/2
−

in the second equation.
y
=

Replace all occurrences of x in y
=
x
/2
−
7
with −
46
/3
.
y
=
−
46

x
=
