Answer:
Step-by-step explanation:
3. Area = pie r2
A = (22/7) (4)2
= 50.27
4. Circumference = pie d
C = (22/7) (13)
= 40.84
Answer:
Step-by-step explanation:
0.126126126... = x
- 1000x = 126.126126...
- 1000x - x = 126
- 999x = 126
- x = 126/999= 42/333= 14/ 111
Numerator is 14
Correct answer is B.14
A variable can be used to represent an unknown amount. Then you write an equation using the variable and based on the information you are given, and you solve the equation to find the unknown amount.
Here is an example.
Mary has money in a bank account. She received $20 for her birthday. She deposited the $20 in her account. After the deposit, she was told the account had a balance of $85. How much money did she have in the account before depositing the $20?
We don't know the amount she had before depositing the $20, so we will call that amount x. x is a letter used as a variable to represent an unknown amount.
She had x dollars in her account before depositing the $20.
After she deposited the $20, she now has x plus 20, or x + 20.
We are told her account now has $85, so x + 20 must equal 85.
That allows us to write an equation which we can then solve to find the amount of money she had in the account before depositing the $20.
x + 20 = 85
Subtract 20 from both sides.
x + 20 - 20 = 85 - 20
x + 0 = 65
x = 65
Since the variable x represents the amount of money in the account before depositing the $20 birthday money, we can now answer the question.
Mary had $65.
Question 1:
Let X be the number of miles you can drive.
you need to multiply the price per mile by the number of miles and add that to the rental fee.
The total cost has to be less than or equal to the total amount of money you can spend.
The equation is : 0.35X + 26.20 ≤ 200
Question 2:
The cost of the six drinks and the cost of X hot dogs need to be equal to or less than the 18 dollars they gave you.
The cost for the 6 drinks can be simplified to be 6.00
The equation would be:
6.00 + 1.75x ≤ 18
This can be simplified by subtracting the cost of the drinks from both sides:
1.75x ≤ 12
Answer:
about 1587
that is the answer to the question
