Just multiply how many miles in one light year (provided in question which is 1 LY = 5.88*10^12 miles) and multiply that by 13.4 and you should get 7.88*10^13 miles for the answer.
Answer:
3(C + 5) = 7
Step-by-step explanation:
Let C = unknown number
The <u>sum</u> of a <u>number and 5</u>:
C + 5
<u>Three times</u> the sum of a number and 5:
3(C + 5)
Three times the sum of a number and 5 <u>is 7</u>:
3(C + 5) = 7
<u>To solve</u>
Use the distributive law: a(b + c) = ab + ac
⇒ 3C + 15 = 7
Subtract 15 from both sides:
⇒ 3C = -8
Divide both sides by 3:
⇒ C = -8/3

Answer:
13,250,000 feet or 13.25 million feet
Step-by-step explanation:
Each person in the line has a shoulder width of 1.325 feet.
For each person, there is a width of 1.325 ft. There are 10 million people.
Since:
10 million = 10,000,000
The total length must be:
Answer: 13,250,000 feet or 13.25 million feet
