The absolute value equation for the values of x = -10 and x =-5 will be |( x + 10 )( x + 5 )| =0.
According to the question.
We have solutions of a absolute value equation.
As we knoaw that, the non-negative value of a real number x without regard to its sign is known as its absolute value or modulus equation in mathematics and is indicated by the symbol |x|.
To find the absolute value equation whose solution are x = -10 and x = -5 we need to add some previous steps, which make the equation an absolute value equation.
|(x+10)(x+5)|=0,
x=-10 and x=-5
Hence, the absolute value equation for the values of x = -10 and x =-5 will be |( x + 10 )( x + 5 )| =0.

An airplane that can travel 450 mph in still air, encounters a 30-mph headwind. How long will it take the plane to travel 1050 miles into the wind?
The time plane will take to travel 1050 miles into the wind is 2.5 hours.
What is speed?Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now given that,
Speed of airplane in still air = 450 mph
Speed of wind = 30 mph
Distance to travel = 1050 miles
So, Actual speed of wind = 450 mph - 30 mph
⇒ Actual speed of wind = 420 mph
So, since Speed = Distance/Time
⇒ Time = Distance/Speed
⇒ Time = 1050/420
⇒ Time = 2.5 hours
Thus, the time plane will take to travel 1050 miles into the wind is 2.5 hours.

a market woman bought n eggs at the rate of 12 eggs at €60. 8 of the eggs were broken so she sold the remaining at the rate of 4 eggs at €24 and made a profit of €12. how many eggs did she buy.
Answer:26 eggs
Step-by-step explanation: yes
The market woman bought 60 eggs.
The market woman bought n eggs at the rate of 12 eggs for €60.
So, the cost price of each egg is given by:
Cost price per egg = €60 / 12 = €5
The total cost of n eggs is the cost price per egg multiplied by the number of eggs (n):
Total cost = €5 * n = 5n
After buying n eggs, 8 of them were broken.
So, the market woman had (n - 8) eggs left to sell.
She sold the remaining eggs at the rate of 4 eggs for €24.
The selling price of each egg is given by:
Selling price per egg = €24 / 4 = €6
The total selling price of the remaining (n - 8) eggs is the selling price per egg multiplied by the number of remaining eggs (n - 8):
Total selling price = €6 * (n - 8) = 6n - 48
The profit is the difference between the total selling price and the total cost:
Profit = Total selling price - Total cost
Since the problem states that the market woman made a profit of €12, we can set up the equation:
6n - 48 - 5n = 12
Solve for n.
Combine like terms:
n - 48 = 12
Add 48 to both sides:
n = 60
So, the market woman bought 60 eggs.

It takes ken 80 seconds to complete one lap
It takes Hamid 60 Seconds to complete one lap

How may laps will they each run when they next meet on the start line?
It is found that Ken will have run 3 laps and Hamid will have run 4 around a track.
What is prime factorization?Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities. Prime factorization is when all those factors are prime numbers.Thus, prime factorization expresses an integer in terms of multiples of prime numbers.
Prime factorization is unique for each integer.
To determine the number of seconds that will have passed when they meet again. We will use the LCM, or least common multiple, for this.
Thus the prime factorization of each number:
80 = 10(8)
10 = 5(2)
8 = 2(4)
4 = 2(2)
80 = 2(2)(2)(5)(2)
60 = 10(6)
10 = 5(2)
6 = 2(3)
60 = 2(2)(3)(5)
For the LCM,
2(2)(5)(2)(2)(3) = 240
This means every 240 sec; they will both be at the start line.
Since Ken completes a lap in 80 seconds, then he will completes
240/80 = 3 laps in 240 seconds.
Since Hamid completes a lap in 60 seconds, then he will completes 240/60 = 4 laps in 240 seconds.
Hence, It is found that Ken will have run 3 laps and Hamid will have run 4.

a gas station sells regular gas for $2.10 per gallon and premium gas for $2.90 a gallon. at the end of a business day 280 gallons of gas had been sold, and receipts totaled $652. how many gallons of each type of gas had been sold?
200 gallons of regular gas and 80 gallons of premium gas were sold.
Let the amount of regular gas sold be x gallons. So, the amount of premium gas sold will be (280 - x).
Now, forming the equation using the given information, to find the amount of each type of gallon.
Equation -
2.10x + 2.90(280 - x) = 652
Performing multiplication with values inside bracket in Left Hand Side
2.10x + 812 - 2.90x = 652
Rewriting the equation -
812 - 652 = 2.90x - 2.10x
Performing subtraction
160 = 0.8x
Rewriting the equation according to x
x = 160÷0.8
Performing division to find the value of x
x = 200
So, 200 gallons of regular gas was sold.
Amount of premium gas sold = 280 - 200
Performing subtraction
Amount of premium gas sold = 80 gallons
Hence, 200 gallons of regular gas and 80 gallons of premium gas was sold.

A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator. The numerator is the number above. While the denominator is the number below
A mixed number is a number that has a whole number and a proper fraction. A proper fraction is a fraction is which the numerator is less than the denominator.
Cups of butter needed = (2/3 x 6) / 16
4 / 16 = 1/4 cups
Ounces of chocolate needed = (5 x 6) / 16

coin $a$ is flipped three times and coin $b$ is flipped four times. what is the probability that the number of heads obtained from flipping the two fair coins is the same?
The probability that the number of heads obtained from flipping the two fair coins is the same is 35/128.
Probability:
Probability means the fraction of favorable outcome and the total number of outcomes.
So it can be written as,
Probability = Favorable outcomes / Total outcomes
Given,
The coin a is flipped three times and coin b is flipped four times.
Here we need to find the probability that the number of heads obtained from flipping the two fair coins is the same.
We know that,
There are 4 ways that the same number of heads will be obtained;
0, 1, 2, or 3 heads.
The probability of both getting 0 heads is
[tex]$\left(\frac12\right)^3{3\choose0}\left(\frac12\right)^4{4\choose0}=\frac1{128}$[/tex]
Probability of getting 1 head,
[tex]$\left(\frac12\right)^3{3\choose1}\left(\frac12\right)^4{4\choose1}=\frac{12}{128}$[/tex]
Probability of getting 2 heads is,
[tex]$\left(\frac12\right)^3{3\choose2}\left(\frac12\right)^4{4\choose2}=\frac{18}{128}$[/tex]
And the probability of getting 3 heads is,
[tex]$\left(\frac12\right)^3{3\choose3}\left(\frac12\right)^4{4\choose3}=\frac{4}{128}$[/tex]
Therefore, the probability that the number of heads obtained from flipping the two fair coins is the same is,
=> (1/128) + (12/128) + (18/128) + (4/128)
=> 35/128.
