SOLUTION
Step 1 : We need to recognize the value of x in 5 places means 5 x
and the value of 1 in 6 times means 6,
so we have that: 5 x + 6 = 1 .
Step 2 : We need the linear equation: 5 x + 6 = 1
collecting like terms, we have that:
5 x = 1 - 6
5 x = - 5
Divide both sides by 5 , we have that:
x = - 1
CONCLUSION : The value of x = -1 ( OPTION B )

O A. x = 3 or 12
OB. x = 3 or -12
O C. x = 6 or -6
OD. no real solution
Answer:
B x = 3 or -12
Step-by-step explanation:
(btw this / is a fraction sign and this ^ is the power of sign)
Let's solve your equation step-by-step.
x^2+9x−36=0
For this equation: a=1, b=9, c=-36
1x^2+9x+−36=0
Step 1: Use quadratic formula with a=1, b=9, c=-36.
x= −b±√b^2−4ac/2a
x= −(9)±√(9)2−4(1)(−36)/2(1)
x= −9±√225/2
= x= 3 or x= -12

Given the function f(x)=2.5xsquared+3, find the average rate of change over the interval 0 ≤ x ≤ 4. What does the average rate of change tell you about the function?
The average rate of change over the interval is 10 and it tells us about the slope
How to determine the average rate of changeThe definition of the function is given as
f(x) = 2.5xsquared + 3
Rewrite the function properly
So, we have the following equation
f(x) = 2.5x² + 3
The interval to calculate the average rate of change is given a
0 ≤ x ≤ 4
This can be represented as
[0, 4]
Further, rewrite as
[a, b] = [0, 4]
Where a = 0 and b = 4
Calculate f(a) and f(b)
So, we have
f(0) = 2.5(0)² + 3 = 3
f(4) = 2.5(4)² + 3 = 43
The average rate of change is then calculated as
Average rate = [f(b) - f(a)]/[b - a]
Substitute the known values in the above equation
So, we have
Average rate = [43 - 3]/[4 - 0]
Evaluate
Average rate = 10
What the average rate tells usThe average rate is the slope of the function
This means that it represents the amount of change in the function with respect to the change in the input variables

Which of the following is equivalent to 2.68?
2.68%
two and seventeen twenty fifths
twenty five seventeenths
26.8%
The expression that is equivalent to the number 2.68 is (b) two and seventeen twenty fifths
How to determine the equivalent number/expression?From the question, we have the following parameters that can be used in our computation:
Number = 2.68
Expand the number using the addition operator
So, we have the following representation
Number = 2 + 0.68
Express 0.68 as a fraction
This gives
Number = 2 + 68/100
Simplify the fraction
So, we have the following representation
Number = 2 + 17/25
This implies that
Number = two and seventeen twenty fifths
Hence, the equivalent of 2.68 is (b) two and seventeen twenty fifths

How many permutations can be formed from all of the letters of the word houston?.
The word "Houston" can have a maximum of 2520 permutations using all it's letters.
As per the question statement, we are provided with a word: HOUSTON.
And we are required to calculate the total number of permutations that can be formed using all the letters of it.
To solve this question, first we will need to determine the number of letters in our concerned word, which in this case is 7, and then number of repeated letters, which is 2, since the letter "O" is repeated once.
Therefore, the total number of permutations that can be formed using all the letters of the word HOUSTON = [(7!)/(2!)]
= (7 * 6 * 5 * 4 * 3)
= 2520

Write an equation involving absolute value for the graph if the points are located at -3.75 and 3.75.
The absolute value equation with the solutions -3.75 and 3.75 is:
|x| = 3.75
How to write the absolute value equation?The general absolute value equation can be written as:
|x+ a| = b
And this can be rewritten into two equations, which are:
x + a = b
x + a = -b
In this case, we want to get an absolute value function such that the two solutions are -3.75 and 3.75, this is ratter trivial to do, we can write the next absolute value function:

Answer:
ST = 63
TU = 63
SU = 126
Step-by-step explanation:
Given that T is the midpoint...
Thus TS = ST and SU = 2ST =2TU
from equation...
9n = 5n + 28
9n - 5n = 28
4n = 28
n = 7
Put the value of n in the equation...
ST = 9n
= 9 x 7
= 63
SU = 9n + 5n + 28
= (9 x 7) + (5 x 7) + 28 = 126

santi and vlado drove together from new york to new orleans. both drove the same amount of time, but santi drove 75% as quickly as vlado. if the drive took a total of 24 hours and new orleans is 1,304 miles from new york, approximately how many miles did santi drive?
If both Santi and Vlado drove for the same amount of time with Santi driving at 75% of Vlado's average speed, and they covered 1304 miles in 24 hours, then Santi had driven for approximately 559 miles.
As per the question statement, Santi and Vlado drove together from New York to New Orleans. Both of them drove for the same amount of time with Santi driving 75% as quickly as Vlado, and it took them 24 hours to complete the 1304 miles journey.
We are required to calculate the approximate number of miles, that Santi drove during their trip.
Since given that, Both of them drove for the same amount of time and it took them 24 hours to complete the 1304 miles journey, therefore, both Santi and Vlado drove for (24/2) = 12 hours each.
Now, let us consider that Vlado drove at an average speed of "v" miles/hour.
Then, Santi would have driven at a average speed of [(75/100)v] m/h
= (0.75v) m/h
= 0.75V miles/hour
[Since Santi drove 75% as quickly as Vlado]
Now as we know that, [(speed * time) = distance], applying the same formula to the velocities and driving times of Santi and Vlado, we get,
[{(12 * v) + (12 * 0.75v)} = 1304]
Or, [(12v + 9v) = 1304]
Or,(21v = 1304)
Or, v = [(1304/21)]
Or, (v = 62.095 miles/hour)
Or, (v ≈ 62.1 miles/hour)
That is, Vlado drove at an average speed of 62.1 miles per hour,
And, Santi drove at an average speed of (62.1 * 0.75) miles per hour
= (46.575) miles per hour.
Therefore, Santi drove a total of (46.575 * 12) = 558.9 miles ≈ 559 miles,
as he drove at an average speed of 46.575 miles per hour, for 12 hours.

How to use inequality to represent a situation?Charlie Brown and Linus are so excited for Halloween that they have planned trips to three different parks.
They are willing to pay no more than $40 to go to all of them.
Jones’ Corn Maze has an entry fee that is $4 less than double the amount of Tomilloso’s Pumpkin Patch entrance fee.
King’s Haunted House has an entry fee that is $2 more than Tomilloso’s Pumpkin Patch.
let
x = amount of Tomilloso’s Pumpkin Patch entrance fee
Therefore, the inequality that represent the situation is as follows;

Therefore,

How many days until Camryn practices the trumpet and flute again in the same day
The greatest number of identical packages that Shaquira can make is 2.
Given data:
Shaquira has made 86 chocolate chip cookies and 42 sugar cookies.
Shaquira wants to create identical packages of cookies to sell, and she must use all of the cookies.
To find:
The greatest number of identical packages that Shaquira can make
In order to find the greatest number of packages, we find the HCF of 86 and 42.
Write down this part from the attached image.
Here, 86 = 1 × 2 × 43, 42 = 1 × 2 × 21
Thus HCF = 1 × 2 = 2
So, Shaquira can make 2 identical packages the most.
Each package will have
(86 ÷ 2) = 43 chocolate chips and
(42 ÷ 2) = 21 sugar cookies.
For questions like these you would need to find out the Least Common Multiple, or L.C.M
If Camryn plays the trumpet and the flute today, and they both are in intervals of 11 and 3 days, you would need to find the LCM for 11 and 3.
LCM:
11 = 11, 1
3 = 3, 1
As they both have no common factors, and are prime numbers, multiply 11 x 3 = 33.
So, the least amount of days required for the trumpet and the flute to be played together is 33 days. And the interval between practising them both on the same day is 33 days.
Hence, the number of days until Camryn practices the trumpet and the flute on the same day is 33 days.
