The annual expenditure of the US federal government is approximately 444 trillion dollars. If a one dollar bill is 0.00010.00010, point, 0001 meters thick, how many meters tall would a stack of 444 trillion one dollar bills be? Write your answer in scientific notation. For reference: 111 trillion =10^{12}=10 12

meters.

Step-by-step explanation:

This question can be solved using a rule of three.

If a one dollar bill is 0.0001 meters thick.

So 1 dollar is m tall.

How tall is 4 trillion one dollar bills?

1 trillion =

So 4 trillion =

Then

1 dollar - m

- xm

The answer is meters.

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
