Answer:
<h3>The number is 500</h3>
Step-by-step explanation:
Let the number be x
The quotient of a number divided by five is written as
![\frac{x}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B5%7D%20)
the number decreased by 400 is written as
x - 400
Equate the two expressions
We have
![\frac{x}{5} = x - 400](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B5%7D%20%20%3D%20x%20-%20400)
Multiply through by 5
That's
x = 5x - 2000
x - 5x = - 2000
- 4x = - 2000
Divide both sides by - 4
x = 500

The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A
let me know if you have any questions!!!
X equals 80 degrees and y equals 130 degrees
Let's evaluate each one of our options to check which one is the better for your wallet.
Option 1: A cash sale for $88
Nothing much to do here, the cost of the bicycle is $88
Option 2: $5 down with equal payments of $8 for 10 weeks
Here you are making an initial payment of $5 and 10 payments of 8$, so let's find the total cost of the bicycle:
Total cost = $5 + 10($8)
Total cost = $5 + $80
Total cost = $85
Option 3: $12 down with equal payments of $5 for 12 months
Here you are making an initial payment of $12 and 12 payments of 5$, so let's find the total cost of the bicycle:
Total cost = $12 + 12($5)
Total cost = $12 + $60
Total cost = $72
Option 4: $20 down with equal payments of $20 for 12 months
Here you are making an initial payment of $20 and 12 payments of 20$, so let's find the total cost of the bicycle:
Total cost = $20 + 12($20)
Total cost = $20 + $240
Total cost = $260
We can conclude that the better option for purchase a bicycle is option 3: $12 down with equal payments of $5 for 12 months.
The following recurring decimal as a rational number are 1/2, 13/100 and 341 / 1000
<h3>What is rational number?</h3>
A rational number is a number that is expressed as the quotient or fraction of two integers, a numerator and a non-zero denominator such as;
3/4. where,
- Numerator = 3
- Denominator = 4
Therefore,
0.5
= 5/10
= 1/2
0.13
= 13/100
0.341
= 341 / 1000
