A number is doubled and then increased by seven. The result is fifty-one. What is the original number?
Answer: I believe it's 22
Step-by-step explanation:
51 - 7 = 44
If the result is 55 and was increased by 7, you'll subtract 7 from 55 and you'll get 44.
44/2 = 22
To find the number that is doubled and makes up 44, you'll divide 2 from 44 and you'll get 22
My work is already late because I was suppose to turn it in at 9:30 PM sooo like help?
solve the equation show each step
-36 = -3x -4 -5x
i believe that would be the answer. im sorry if its wrong-
Answer:
4 = x
Step-by-step explanation:
To solve for the value of x
-36 = -3x -4 -5x
Transpose and solve
-36 = -8x -4
-36 + 4 = -8x
-32 = -8x
-32 ÷ -8 =x
Both the negative signs will be cancelled
4 = x

Answer:
D. Subtract 15 cents and add 29 cents
Step-by-step explanation:
He should subtract 15 cents and add 29 cents. This is because at 33.85 we estimated to 34 dollars which was 15 cents higher, so we must subtract by 15 to get to the exact cost. We also need to add 29 cents since we rounded down from 16.29 to 16.
Salaries for teachers in a particular elementary school district are normally distributed with a mean of $41,000 and a standard deviation of $7,200. We randomly survey ten teachers from that district. (Round your answers to the nearest dollar.)
(a) Find the 90th percentile for an individual teacher's salary.
$
(b) Find the 90th percentile for the average teacher's salary.
$
Using the normal distribution and the central limit theorem, it is found that:
a) The 90th percentile for an individual teacher's salary is $50,216.
b) The 90th percentile for the average teacher's salary is $43,914.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
Mean of $41,000, thus [tex]\mu = 41000[/tex].Standard deviation of $7,200, thus [tex]\sigma = 7200[/tex].Item a:
The 90th percentile is X when Z has a p-value of 0.9, so X when Z = 1.28. Thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.28 = \frac{X - 41000}{7200}[/tex]
[tex]X - 41000 = 1.28(7200)[/tex]
[tex]X = 50216[/tex]
The 90th percentile for an individual teacher's salary is $50,216.
Item b:
Average for a sample of 10, thus [tex]n = 10, s = \frac{7200}{\sqrt{10}}[/tex].
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]1.28 = \frac{X - 41000}{\frac{7200}{\sqrt{10}}}[/tex]
[tex]X - 41000 = 1.28\frac{7200}{\sqrt{10}}[/tex]
[tex]X = 43914[/tex]
The 90th percentile for the average teacher's salary is $43,914.

Kurt deposited money into his bank account every month. The amount of money he deposited in the first 5 months of 2014 is listed in the table.

(dollars)
January 1,200.32
February 985.43
March 1,200.65
April 1,987.34
May 1,000.98
The total amount of money that Kurt had deposited into his account at the end of May is
$6,374.72
. The total amount of money that he had deposited into his account at the end of March is
.
Reset
9514 1404 393
Answer:
$3386.40
Step-by-step explanation:
The amount at the end of March can be found two ways:
add up the deposits for Jan, Feb, Mar:
1200.32 +985.43 +1200.65 = 3386.40
subtract Apr and May from the May total:
6374.72 -1000.98 -1987.34 = 3386.40
The total amount of money that he had deposited into his account at the end of March is $3386.40.
A representative from the bank speaks with you about opening a savings product. You would be guaranteed at least a 3.5% return for the next 10 years when you agree to add $25.00 each month for the entire time. Given this information and that you meet the minimum monthly contribution requirement, what would be your total accumulated value at the end of the 10 years?
Answer:
a 3.5 % return is .035/12 - .002917 / mo
10 years is 120 mos.
This is basically an annuity payment - after 10 years 1$, deposited monthly, would be worth (similar to house mortgage, etc.)
N = (1 - (1 + i)^-120) / i = 241.73
Total amount = 25 * 241.73 = 6043
Note 120 payments at $25 = 3000

Deon plans to ride a 15 mile bicycle trail. If his average speed is 20mi/h, which equation can he use to find the time t, in hours, for the ride?
Answer
15=20t
Step-by-step explanation:
Answer:
t = 15 / 20
Step-by-step explanation:
Given:
Distance traveled by Deon to ride a bicycle trail = 15 mile
Average speed of Deon to ride a bicycle trail = 20 mi/hour
Step-by-Step:
Let 'T' be the time taken to ride the bicycle trail.
We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.
[tex]Distance=\frac{Speed}{Time}[/tex]
Distance = 15 miles
Speed = 20 miles / hour
Time = 15 / 20
Assuming time is t, the formula would be:
t = 15 / 20
"t = 15 mi/ 20 mi/hr " will help Deon calculate the time he will take.
Therefore, t = 15 / 20

identify the solutions of the inequality 5 ≤ s − 6
Answer:
s≥11
Step-by-step explanation:
5 ≤ s -6
=5 + 6 ≤ s
=11 ≤ s or s≥11
The solution to given inequality 5 ≤ s − 6 for s will be s ≥ 11.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Given the inequality,
5 ≤ s − 6
Subtracting by 5 on both sides,
5 - 5 ≤ s - 6 - 5
0 ≤ s - 11
Adding 11 on both sides
0 + 11 ≤ s - 11 + 11
11 ≤ s or s ≥ 11
Hence "The solution to given inequality 5 ≤ s − 6 for s will be s ≥ 11".
