The product of 9 and a number is 12 less than three times that number.

What is the number?

_____

Final answer:

To find the solution set for the inequality x - 5 > -10, add 5 to both sides resulting in x > -5; hence the solution set is {x | x ∈ R, x > -5}.

Explanation:

The student is asking for the solution set for the inequality x - 5 > -10. To solve for x, we need to isolate the variable on one side of the inequality. Add 5 to both sides of the inequality to achieve this:

This means that the value of x must be greater than -5. We can represent this solution set as {x | x ∈ R, x > -5}, where R represents the set of all real numbers.

Comparing this solution to the given options, it is clear that the correct solution set is the second one: {x | x ∈ R, x > -5}.

The expression that will represent Cindy’s bill is 0.95(1.09m + 2.79n). Hence, the correct option is D. 0.95(1.09m + 2.79n).

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

It is given that store sells 12-packs of ballpoint pens for $1.09 each.

The store also sells composition books for $2.79 each.

Cindy buys 'm' packs of ballpoint pens and 'n' composition books.

So, the equation for this becomes

1.09m + 2.79n

Cindy gets a 5% discount, so she has to pay 95% of the regular price.

Then the expression that will represent Cindy’s bill,

0.95(1.09m + 2.79n)

Hence, the correct option is D. 0.95(1.09m + 2.79n).

Step-by-step explanation:

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where π can be approximated as 3.14 for simpler calculations. Volume is proportional to the cube of the radius, so if the radius changes significantly, the volume adjusts correspondingly by the cube of the factor of change.

To calculate the volume of a sphere using the value 3.14 for pi, you can apply the formula V = (4/3)πr³. If the radius of the sphere is 'r', you would plug in the value of 'r' into this formula. Next, you would multiply the result by 4/3 and then by 3.14 in place of π to get the volume. It's important to note that the volume of the sphere increases proportionally to the cube of the radius, meaning if the radius changes by a factor of 10, the volume changes by a factor of 10³ or 1000.

Bayley can hit a single golf ball every 5 minutes

Now Bayley can hit 42 golf balls in 3 1/2 hours

Thus converting the 3 1/2 hours in minutes:

3 hours +  1/2 hours = 180 minutes + 30 minutes = 210 minutes

Bayley can hit 42 golf balls in 210 minutes

Thus let's say she takes 'x' minutes to hit one ball

Calculating the value of 'x'  using direct proportion theorem:

[tex]\frac{x}{210}=\frac{1}{42}[/tex]

[tex]x*42 = 210[/tex]

[tex]x= \frac{210}{42}[/tex]

[tex]x = 5[/tex]

Thus Bayley can hit 5 golf balls every 1 minute

Given that,
To justify whether tim estimates that 60÷5.7 is about 10. Will the actual quotient be greater than or less than 10

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Dividend = 60
Divisor = 10
Now,
= 60/ 5.7
= 10.52 = quotient which is greater than 10

Answer: a) Fraction of the total sales did each salesperson sell:-

[tex]\text{Lola}=\frac{203}{537}[/tex]

[tex]\text{Ahmed}=\frac{154}{537}[/tex]

[tex]\text{Tommy}=\frac{180}{537}[/tex]

b) Each person receive=$33

Step-by-step explanation:

Given: The three salespeople for a local advertising firm are Lola, Ahmed, and Tommy.

Sales by Lola= $2030

Sales by Ahmed=$1540

Sales by Tommy=$1800

Thus, the total sales= $2030+$1540+$1800=$5370

Fraction of the total sales did each salesperson sell:-

[tex]\text{Lola}=\frac{\text{Sales by Lola}}{\text{total sales}}=\frac{2030}{5370}=\frac{203}{537}[/tex]

[tex]\text{Ahmed}=\frac{\text{Sales by Ahmed}}{\text{total sales}}=\frac{1540}{5370}=\frac{154}{537}[/tex]

[tex]\text{Tommy}=\frac{\text{Sales by Tommy}}{\text{total sales}}=\frac{1800}{5370}=\frac{180}{537}[/tex]

After calculating the total reduction in the bank account balance, it was determined that each of the two equal checks cashed was for the amount of $140.41.

The problem at hand is a simple algebra question where we are solving for the amount of each check cashed when a bank account balance changes from a positive balance to a negative one.

Firstly, we must establish the initial and final bank balance amounts before and after the checks are cashed. We know that the beginning balance was $235.24 and after cashing two identical checks, the balance becomes -$45.58. The total reduction in the bank account reflects the total amount of the two checks combined.

To find the total reduction, we subtract the final balance from the initial balance:

Total reduction = Initial balance - Final balance

Total reduction = $235.24 - (-$45.58) = $235.24 + $45.58 = $280.82

Since there were two checks with equal amounts, we divide the total reduction by two to find the amount of each check:

Amount per check = Total reduction / 2

Amount per check = $280.82 / 2 = $140.41

Therefore, the amount of each check was $140.41.
