If you rewrite this phrase to be an equation, with N representing the missing number, it would be:
20% x N = 1581.01 or 0.2N = 1581.01
This equation basically says 20% of what number equals 1581.01.
To get to the answer, divide both sides by 0.2. -->
0.2N ÷ 0.2 = 1581.01 ÷ 0.2 -->
N = 1581.01/0.2
N = 7905.05
Information given:
- <u>100 passengers in each train car</u>
- <u>10 train cars total</u>
- <u>30 trains total</u>
<em>So we are trying to find the total number of passengers on all 30 trains?</em>
<u />
Step-by-step:
100 x 10 = <u>1,000 passengers per train</u>
1,000 x 30 = <u>30,000 passengers total within the 30 trains</u>
Answer: <u>30,000 passengers</u>
<em>Hopefully this answered your question :)</em>
6 = 5r - 14
6 + 14 = 5r
20 = 5r
r = 4
<h2><u>
ABSOLUTE VALUE</u></h2>
The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.
<h3>Exercise</h3>
Replace the value of x:



The absolute value of a number is the numerical value of the number, without regard to its sign.
<h3><u>Answer.</u> 12</h3>
The answer would be 2(6x+5+2y) you can figure this out through the distributive property. 2(6x)=12x 2(5)=10 and 2(2y)= 4y this would reult in giving you the equation 12x+10+4y
