Four more than the product of a number and 9 equals 6.
Use the variable w for the unknown number.
Answer:
9w+4=6 I believe is the answer
The translation of four more than the product of a number and 9 equals 6 into an equation is 9w + 4 = 6
Given,
Four more than the product of a number and 9 equals 6.
We need to translate the sentence into an equation.
What is the meaning of some important mathematical terms?- More than means we need to add.
- Product means we need to multiply.
- Equals means =
- Sum means adding
- Less than means we need to subtract.
Translate the given sentence into an equation.
Four more than = + 4
Let the number be w.
the product of a number and 9 = w x 9
We get,
9w + 4 = 6
Thus the equation is given by 9w + 4 = 6.

Henry is three more than twice Nicholas’ age. Marcus is 9 less than six times Nicholas’s age. If Henry and Marcus are twins, how old is Nicholas?
Answer:
Step-by-step explanation:
Henry is 3 more than twice Nicholas' age. You can write this as :
H = 3 + 2N
Marcus is 9 less than 6 times Nicholas' age:
M = 6N - 9
Since Henry and Marcus are twins, this means H = N.
3 + 2N = 6N - 9
Add 9 to both sides
12 + 2N = 6N
Subtract 2N from both sides
12 = 4N
Divide both sides by 4 to find N.
N = 12/4 = 3
A team of college administartors caputured and atgged a group of 90 fraternity men and then returned them to the universiry campus. Later a group of soroity women wishing to stimate the amount of fraternity men on campus caputred 215 men and found they were tagged. How many frat men would they stimate that were on campus
Answer:
125
Step-by-step explanation:
The college administrators captured the 90 fraternity men and tagged them, then they returned them to the university campus.
Let there were x tagged fraternity men already on the university campus, so, the total number of tagged fraternity men on the campus become x+90.
Later a group of sorority women captured 215 tagged men, in which the 90 tagged men added by the college administration are included.
So, x+90=215
[tex]\Rightarrow x=215-90=125.[/tex]
Hence, the number of fraternity men on the campus was 125.

James and Tyree have new jobs at YumYum’s Ice Cream Parlor. James is Tyree’s manager. In their first year, James will be paid $14 per hour and Tyree will be paid $7 per hour. They have been told that after every year with the company, they will each be given a raise of $2 per hour. Is this realationship porprotional?
Answer:
No.
Step-by-step explanation:
(h represents the hours; y represents years; m represents the total money they'd get!)
If you put this into an equation, for James it would be:
14h +2y = M
For Tyree, it would be:
7h + 2y = M
Because the numbers don't match up, the answer is no. The relationship is not proportional.
Which sum does the model below represent?
4 positive tiles and 7 negative tiles.
4 + (negative 7) = negative 3
4 + 7 = 11
8 + (negative 3) = 4
11 + (negative 4) = negative 3
The sum the model below represents will be 4 + (negative 7) = negative 3. Option A is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, the expression is 4 positive tiles and 7 negative tiles. We have to apply summation for the given expression,
Expression is the combination of constants and variables with mathematical operators.
The model is algebraically solved as,

Jada is planning a kayak trip. She finds an expression for the time, T(s), in hours it takes her to paddle 10 kilometers upstream in terms of s, the speed of the current in kilometers per hour. This is the graph Jada gets if she allows s to take on any value between 0 and 7.5. What would be a more appropriate domain for Jada to use instead?
Answer:
A more appropriate domain would be all real numbers except x = 5.5
Step-by-step explanation:
Given that the domain of a rational function consists of the set of real numbers but excluding those real numbers that results in a zero in the denominator
The given graph of the function has a vertical asymptote at s = 5.5 which indicates a value for which the function is not defined and at x = 5.5, and as such the value (5.5) of the asymptote is not a member of the function's domain
The values of the domain of a function consisting of a reciprocal must exclude does that result in a zero denominator.
The domain of the function that represents Jada's trip is the set of input value the function can take
The appropriate domain is: all real numbers except x = 5.5
From the graph, we can see that:
The x-value starts at negative infinity, and ends near 5.5The x-value then continues near 5.5, and ends at positive infinityThis means that the input of the graph cannot be 5.5
Hence, an appropriate domain would be: [tex]\mathbf{x \ne 5.5}[/tex]
