Lets see, If "n" represents the number, then "the successor of a certain number" is n+1. Now if "Twice the number" is 2n now for the expression "The successor of a certain number when added to twice the number" would then be 2n+n+1, which the problem stated is equal to 61 Therefore we can say that the correct option would be 2n+n+1=61
A=LWH
divide both sides by LW
A/(LW)=H
Answer:
9
Step-by-step explanation:
its going up every 9
5+9=14
14+9=23
23+9=32

Considering the given proportion of $100 every 4 minutes, the earnings are as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The proportion for this is of $100 every 4 minutes, hence the amount per minute is:
$100/4 = $25.
The amount per hour(60 minutes) is:
25 x 60 = $1,500.
In 12 hours, the amount is:
12 x 1500 = $18,000.
In 24 hours, the amount is:
25 x 1500 = $36,000.

(<em>q = quarters, n = nickles</em>)
<u>First, create your system of equations:</u>
25q + 5n = 535 cents
n = 2q - 5
<u>Second, Substitute for n:</u>
25q + 5(2q - 5) = 535
<u>Simplify:</u>
25q + 10q - 25 = 535
<u>Simplify to solve for q:</u>
35q=560
q=16
<u>Next, solve for n by plugging the value of q back into the equation:</u>
n=2q - 5
n=32-5
n=27
There would be 16 quarters and 27 nickles.
