Answer:

D

Step-by-step explanation:

7 - z = 3 + z + 4 - 2z

7 - 3 - 4 = z - 2z + z

0 = 0 (Infinitely many solutions)

5(a + 4) - 15 = -5(a - 1)

5a + 20 - 15 = -5a + 5

5a + 5a = 5 - 20 + 15

10a = 40

10a/10 = 40

a = 4

(one solution)

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

2d - 4 = 5 + 3d - 9

2d - 3d = 5 - 9 + 4

- d = 0

d = 0

(one solution)

-11(n - 2) + 8(n + 1) = -3(n + 10)

-11n + 22 + 8n + 8 = -3n - 30

-11n + 8n + 3n = -30 - 22 - 8

0 = -60

(no solutions)

If you had 1 billion dollars all in $100 dollar bills, how many times could they
RUDIKE [14]

Answer: 1.94 times.

Step-by-step explanation:

Lenght of $100 dollars = 6.14 inches

Lenght of North Carolina = 500 miles long.

Now, in 1 billon = 1,000,000,000

If we divide it by the value of each bill, we will found the number of bills, we have:

N =  1,000,000,000/100 = 10,000,000 bills.

Knowing that each bill is 6.14 inches long, the length of the N bills together is:

6.14in*10,000,000 = 61,400,000 in

Now we need to write this in miles; 63,360 inches is one mile.

Then  61,400,000 in =  (61,400,000/63,360) = 969.1 miles.

Now we can find that:

969.1mi/500 mi = 1.94

This means that with 1 billion dollars all in $100 dollar bills we can stretch them 1.94 times along the length of North Carolina.
