Answer: B. 6
Step-by-step explanation:
Let x be the [certain number]
Rephrase the expression
13 less than fourteen times a certain number is twenty-nine more than 7 times that number
14x-13=7x+29
Calculate
Given
14x-13=7x+29
Add 13 on both sides
14x-13+13=7x+29+13
14x=7x+42
Subtract 7x on both sides
14x-7x=7x+42-7x
7x=42
Divide 7 on both sides
7x/7=42/7
x=6
Hope this helps!! :)

Derive standard form of an equation of a circle with center C(5,2) and radius r=4, using the Pythagorean theorem.
Answer:
(x-2)^2 + (y - 5)^2 = 16
Step-by-step explanation:
Given the standard form of an equation of a circle
(x-h)^2+(y-k)^2=r^2
If (h, k) = (5,2) and r = 4
Substitute
(x-2)^2 + (y - 5)^2 = 4^2
(x-2)^2 + (y - 5)^2 = 16
Hence the required equation is (x-2)^2 + (y - 5)^2 = 16

Answer:
The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.
Step-by-step explanation:
Physically speaking, average speed ([tex]\bar v[/tex]), measured in miles per hour, is the distance travelled ([tex]\Delta s[/tex]), measured in miles, divided by time ([tex]\Delta t[/tex]), measured in hours. That is:
[tex]\bar v = \frac{\Delta s}{\Delta t}[/tex] (1)
The time needed by the vehicle is:
[tex]\Delta t = 72\,min\times \frac{1\,h}{60\,min}[/tex]
[tex]\Delta t = 1.2\,h[/tex]
If we know that [tex]\Delta s = 143\,mi[/tex] and [tex]\Delta t = 1.2\,h[/tex], then the average velocity of the car is:
[tex]\bar v = \frac{143\,mi}{1.2\,h}[/tex]
[tex]\bar v = 119.167\,\frac{m}{s}[/tex]
The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.
Estimate the equation of the line of best fit for the following graphs.
Step-by-step explanation:
the one on the left (b)
y= mx+b
at x= 0 y = -2
then b= -2
at x= -1 y= 1
1= -m -2
m= -3
y= -3x -2
......
the one on the right side (d)
at x= 2 y = 1
at x= 4 y = 2
1= 2m+b
2= 4m +b
subtract
1= 2m
m= 1/2
y= 1/2 x

1. Gloria says the two expressions - (12x + 24) - 9x and -6(x + 1) are equivalent. Is she correc Explain how you know.
Answer:
No they aren't equivalent
Step-by-step explanation:
Let's take each expression
the first one is
- (12x+24) - 9x = -12x -24 -9x = -21x -24 = -3 (7x +8)
the second expression
-6 (x+1) = -6x-6
So they aren't equivalent
Angel has xx dimes and yy nickels. He has at most 13 coins worth no less than $0.95 combined. Solve this system of inequalities graphically and determine one possible solution.
Answer:
a possible solution is (10,1)
Step-by-step explanation:
Here, we want to solve the given inequality and determine one possible solution
From the question, we have it that;
x + y ≤ 13
Mathematically, we have it that 1 dime is worth $0.1
A nickel is worth $0.05
0.1x + 0.05y ≥ 0.95
please check the attachment for the graph of both equations
The point of intersection represents the solution.
we have a point here as (10,1)

Express the ratio of the following
With
Solution
Answer:
29:17
17:46
29:46
17:29
Step-by-step explanation:
In this problem, we are given three quantities and all we have to do is to write ratios relating two of them. Since all the numbers are relatively prime, we can no longer simplify the ratios.
Problem 1:
29 girls is to 17 boys
29:17
Problem 2:
17 boys is to 46 learners
17:46
Problem 3:
29 girls is to 46 learners
29:46
Problem 4:
17 boys is to 29 girls
17:29
In these problems, it's usually as simple as putting two or three numbers together and reducing them into simplest form.

Ivan and tanya share £150 in the ratio 4 : 1 work out how much more ivan gets compared to tanya.
Answer:
Ivan receives £120 more than Tanya.
Step-by-step explanation:
Total Money = £ 150
Ratio = 4:1
This means that Ivan gets 4x of £150 and Tanya gets 1x of £150.
Ivan's money = 4x
Tanya's money = 1x
Now, we know that total money is equal to the sum of Ivan's & Tanya's money.
Total money = Ivan's money + Tanya's money
£ 150 = 4x + 1x
£ 150 = 5x
150/5 = x
30 = x.
We have found the value of x, now we can substitute 30 in the place of x and find the money Ivan and Tanya get.
Ivan = 4x = 4×30 = £120.
Tanya = 1x = 1×3 = £30.
So, Ivan receives more money. But how much more? We can solve that by subtracting Tanya's money from the total amount.
Total amount - Tanya's money = 150 - 30 = £120.
So, Ivan receives £120 more than Tanya.

1. Solve for w
21+2w=p
2. Solve for a
2a+b=c
3. Solve for a
b-2a=c
1.
Step 1: Flip the equation.
p=2w+21
Answer:
p=2w+21
2.
Step 1: Add -b to both sides.
Step 2: Divide both sides by 2.
Answer:
a= −1 /2b+1/2 c
3.
Step 1: Add 2a to both sides.
−2a+b+2a=c+2a
b=2a+c
Answer:
b=2a+c

Answer:
Step-by-step explanation:
we have the mean=13
(x+y+z)/3=13
x+y+z=39
range=highest value-lowest value=10
lets say x= highest value
y=lowest value
x-y=10
x=10+y
the numbers are 9,11,19

A student has 6 nickel 14 dimes and 8 quarter.what is the ratios of the total number of coins to the number of nickels ? In simplest form
Given:
A student has 6 nickel 14 dimes and 8 quarter.
To find:
The ratio of the total number of coins to the number of nickels.
Solution:
We have,
Number of nickels = 6
Number of dimes = 14
Number of quarter = 8
Total number of coins = 6+14+8
= 28
Now, the ratio of the total number of coins to the number of nickels is
[tex]Ratio=\dfrac{\text{Total number of coins}}{\text{Number of nickels}}[/tex]
[tex]Ratio=\dfrac{28}{6}[/tex]
[tex]Ratio=\dfrac{14}{3}[/tex]
[tex]Ratio=14:3[/tex]
Therefore, the ratio of the total number of coins to the number of nickels is 14:3.

Your research shows that you typically receive a 24% return response from the guest satisfaction surveys you send out. How many guest satisfactions surveys will you need to send out to make certain you receive at least 300 surveys back?
Answer:
1250
Step-by-step explanation:
The number of guest satisfaction surveys will you need to send out to make certain you receive at least 300 surveys back is 1,250.
Calculation of the number of guest satisfaction:Since the return is received i.e. 24%
And, there are the minimum of 300 surveys
So, based on this, the no of guest satisfaction should be
[tex]= 300 \div 0.24[/tex]
= 1,750
hence, The number of guest satisfaction surveys will you need to send out to make certain you receive at least 300 surveys back is 1,250.
