The us postal service delivered 7.14 x 1010 pieces of mail in the month of december and 3.21 x 1010 in the month of january. what is the total mail delivered for these two months? a) 1.035 x 109 b) 1.035 x 1010 c) 1.035 x 10-10 d) 1.035 x 1011 someone fastt!

The postal service delivered:

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)

The correct answer for this problem is

d) 1.035 x 10^11

Step-by-step explanation:

I know this because I just did the test

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
