An absolute value equation with solutions -10 and -5 is |x + 7.5| = 2.5. This is determined by finding the midpoint between -10 and -5, and then expressing the equation to reflect that distance.
To write an absolute value equation that has the solutions x=-10 and x=-5, you must consider the midpoint between these two solutions. The midpoint or average is found by adding the values together and dividing by 2, which we can write as (x + 10 + x + 5)/2. Simplifying, we get (2x + 15)/2 = x + 7.5 as the midpoint. Now an absolute value equation that holds the given solutions will have its vertex (the point where the absolute value expression equals zero) at this midpoint and the same distance from both -10 and -5, which is 2.5 units. So, the equation looks like |x + 7.5| = 2.5.

Rose's stamp collection is 7 less than half of Van's stamp collection, x.
Which expression represents the total number of stamps that Rose has?
The expression representing Rose's stamp collection is given by R = (1/2)x - 7. It denotes that Rose's collection is 7 less than half of Van's stamp collection, where x represents the total number of stamps in Van's collection.
Let's denote Van's stamp collection as x. According to the given information, Rose's stamp collection is 7 less than half of Van's stamp collection.
Expression for Rose's stamp collection (R):
R = (1/2)x - 7
Here's the breakdown of the expression:
(1/2)x represents half of Van's stamp collection.
-7 signifies 7 less than half of Van's stamp collection.
This expression encapsulates the relationship between Rose's stamp collection and half of Van's collection, diminished by 7.

Two cars on a roller coaster hold 14 riders combined. If 12 cars are linked together, how many riders can fit on the roller coaster at one time? Explain how to solve this problem.
Answer:
The rate of riders to cars is 14 divided by 2. So the unit rate is 7 riders per car. Multiply 7 riders by 12 cars to find that 84 riders can fit on the roller coaster at one time.

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold?
Answer:
There are 15 boxes of 10 oz boxes
Step-by-step explanation:
Let the number of boxes of 10 oz = x
and let the number of boxes of 16 oz = y
By the statement
"Total number of boxes sold is 24"
Equation for the statement will be
x + y =24 ---------------(1)
By the statement
"she collected $97.50 while rate of 10 oz box is $3.50 and rate of 16 oz box is $5.00."
Equation for the statement will be
1.5x + 5y = $97.50 ------------(2)
From equation (1) we put the value of y = 24 - x in equation (2)
1.5x + 5(24 - x) = 97.50
1.5x + 120 - 5x = 97.50
-3.5x = 97.50 - 120
3.5x = 22.50
x = [tex]\frac{22.5}{1.5}[/tex]
x = 15
Therefore, number of 10 oz boxes is 15.

Sven is trying to find the maximum amount of time he can spend practicing the five scales of piano music he is supposed to be working on. He has 70 minutes to practice piano and would like to spend at least 55 minutes playing songs instead of practicing scales. So, Sven sets up the following inequality, where t is the number of minutes he spends on each scale, and solves it.
70 − 5t ≤ 55
−5t ≤ −15
t ≥ 3
Sven has concluded that he should spend 3 minutes or more on each scale. Is this correct? If not, what mistake did he make? Then solve for the correct answer.
Answer:
He should spend 3 minutes or less on each scale
Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal
Step-by-step explanation:
Let
t ------> is the number of minutes he spends on each scale
Remember that the phrase "at least" is equal to "greater than or equal"
so
The inequality that represent this scenario is
[tex]70-5t \geq 55[/tex]
solve for t
[tex]-5t \geq 55-70[/tex]
[tex]-5t \geq -15[/tex]
Multiply by -1 both sides
[tex]5t \leq 15[/tex]
Divide by 5 both sides
[tex]t \leq 3[/tex]
Sven is incorrect
He should spend 3 minutes or less on each scale
Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal
Answer:

What's the prime factorization of 105
The prime factorisation of 105 is therefore 3 * 5 * 7.
Prime factorizationWe can factorize 105 into its prime factors by dividing it by prime numbers up to the point when we can no longer divide it. Here is how it works:
Divide 105 by the following prime number, 3, for a result of 35.
35 divided by the following prime number, 5, yields a result of 7 that is:
35/5 = 7
The seventh prime number has been reached. The prime factorisation of 105 is therefore 3 * 5 * 7.
Thus, 3 * 5 * 7 is the prime factorization of 105.

Which function represents a horizontal shift of f(x)=5^x by 4 units to the right?
Answer: [tex]g(x)=5^{x-4}[/tex]
Step-by-step explanation:
When a function f(x) is shifted horizontally by n units to the right , the new function will become :-
[tex]g(x)=f(x-n)[/tex]
The given function : [tex]f(x)=5^x[/tex]
Now, if the given function shifted 4 units to the right , then the new function will become :
[tex]g(x)=f(x-4)[/tex]
[tex]g(x)=5^{x-4}[/tex]
Hence, the function represents a horizontal shift of [tex]f(x)=5^x[/tex] by 4 units to the right will be :-
[tex]g(x)=5^{x-4}[/tex]

What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
The fraction [tex]2\frac{3}{8}[/tex] can be written as 19/8
Let x be the number added to given fraction, that is
19/8 +x=6
⇒ x=6-19/8
⇒ x= (48-19)/8
⇒ x= 29/8
⇒ x= [tex]3\frac{5}{8}[/tex]
Hence, the number must be added to [tex]2\frac{3}{8}[/tex] to make 6 is [tex]3\frac{5}{8}[/tex].
