Eleven less than seven times a number is five more than six times the number.
Answers
The problem is a simple algebraic equation in the form 7x - 11 = 6x + 5. By rearranging and simplifying, we find the solution is x = 16.
Explanation:The question presents a mathematical statement that needs to be solved for the variable. Translating the words into an equation, we get: 7x - 11 = 6x + 5. This equation is saying seven times a number (we'll call it 'x') reduced by eleven is equal to six times that number increased by five.
To solve for 'x', first, rearrange the equation to get all 'x' terms on one side and constants on the other. By subtracting 6x from both sides, we get x - 11 = 5. Then, add 11 to both sides to isolate 'x': x = 16.
So, the number or 'x' that satisfies this equation is 16.

x = 16.
To solve this, let the unknown number be represented by x.
We can set up the equation based on the given information:
7x - 11 = 6x + 5
Subtract 6x from both sides of the equation:
7x - 6x - 11 = 6x - 6x + 5
Simplify the equation:
x - 11 = 5
Add 11 to both sides:
x - 11 + 11 = 5 + 11
Simplify the equation:
x = 16
Thus, the number is 16.
Maria, bill, and change sent a total of 71 text messages during the weekend. change sent 2 times as many messages as bill. maria sent 7 more messages than bill. how many messages did they each send?
Answers
Change sent 2 times as many messages as Bill, or, using our variable for Change and Bill:
[tex]c=2b[/tex]
We're also given that Maria sent 7 messages more than Bill, which we can represent with:
[tex]m=b+7[/tex]
Notice that m and c are both in terms of b. We can use this for our next step. We're given at the beginning that together, Maria, Bill, and Change sent 71 messages over the weekend. As an equation using all of our variables, this translates to:
[tex]m+b+c=71[/tex]
Since m and c are both in terms of b, we can substitute those expressions in and solve for b:
[tex](b+7)+b+2b=71\\ b+7+b+2b=71\\ 7+4b=71\\ 4b=64\\ b=16[/tex]
Now that know that Bill sent 16 texts, we can find the numbers for Change and Maria:
[tex]m=b+7=16+7=23\\ c=2b=2(16)=32[/tex]
So, Bill sent 16 texts, Maria sent 23, and Change sent 32.

Solve for y.
4y = 144
What is the answer?
Answers
/4 /4
4 is canceled out
y=144
/4
144/4 = 36
y = 36
The solution is y = 36. Divide both sides of the equation by 4 to isolate y. To isolate y, we want to get rid of the coefficient 4 that is multiplying y.
We do this by dividing both sides of the equation by 4:
4y / 4 = 144 / 4
On the left side, the 4 in the numerator and the 4 in the denominator cancel out, leaving us with just y:
y = 144 / 4
Now, Simplify the equation.
Now, we can perform the division to find the value of y:
y = 36

find the coordinates of the midpoint of EF with endpoints E(-2,3) and F(5, -3)
Answers
The coordinates of the midpoint of line segment EF with endpoints E(-2,3) and F(5, -3) are (1.5, 0), calculated using the midpoint formula.
To find the coordinates of the midpoint of line segment EF with endpoints E(-2,3) and F(5, -3), you can use the midpoint formula which is:
( (x1 + x2)/2, (y1 + y2)/2 )
Let's apply the formula:
x-coordinate of midpoint = ( (-2) + 5 ) / 2 = 3 / 2 = 1.5
y-coordinate of midpoint = ( 3 + (-3) ) / 2 = 0 / 2 = 0
So the midpoint of EF is (1.5, 0).
Max spent $53 and now has no money left. How much did he have before his purchase
Answers
An equation is formed when two equal expressions. The amount Max had before his purchase is $53.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that Max spent $53 and now has no money left. Therefore, we can write the details as,
The amount spent on the purchase = $53
The amount left after purchase = $0
Let the amount before purchase be represented by M. Therefore, we can write the amount remaining after purchase as,
Amount before purchase - Amount spent on purchase = Amount remaining after purchase
M - $53 = $0
Adding 53 on both sides.
M - 53 + 53 = 53
M = 53
M = $53
Thus, the amount Max had before his purchase is $53.

Determine whether each conjecture is true or false given: n is a real number
Conjecture: n^2 (squared) is a nonnegative number
Answers
The square of all negative and positive numbers is positive, and the square of zero is zero, so the conjecture is true.
The conjecture that any real number squared is a nonnegative number is correct. This is because squaring a positive number gives a positive result, squaring a negative number also gives a positive result, and squaring zero equals 0, which is nonnegative.
Explanation:This mathematical conjecture proposes that for any real number, when squared, the result is a nonnegative number. Given n is a real number, the conjecture n^2 is a nonnegative number is indeed true. In mathematics, a real number is considered nonnegative if it is greater than or equal to zero.
To provide more insight, let's look at a few examples: If we take a positive number such as 3, and you square it (3^2), you get 9, which is a positive number. Equally, if you take a negative number like -3 and square it (-3^2), you get 9 again, which is also a positive number. Even if you take the number zero (which is neither positive nor negative) and square it, you get 0, which is still considered nonnegative. Thus, any real number when squared is always a nonnegative number.

One number is three more than twice another, the sum of the numbers is 12. find the two numbers
Answers
_______________________________________________________
Explanation:
_______________________________________________________
Let "x" represent one of the two (2) numbers.
Let "y" represent the other one of the two (2) numbers.
x = 2y + 3 ;
x + y = 12 .
__________________________
Method 1)
__________________________
x = 12 − y ;
Plug this into "x" for "2y + 3 = x" ;
→ 2y + 3 = 12 − y ;
Add "y" to each side of the equation; & subtract "3" from each side of the equation ;
→ 2y + 3 + y − 3 = 12 − y + y − 3 ;
to get: 3y = 9 ;
Divide each side of the equation by "3" ;
to isolate "y" on one side of the equation; & to solve for "y" ;
3y / 3 = 9 / 3 ;
y = 3 .
____________________________
Now: x = 12 − y ; Plug in "3" for "y" ; to solve for "x" ;
→ x = 12 − 3 = 9
____________________________
So; x = 9, y = 3 .
____________________________
Method 2)
____________________________
When we have:
____________________________
x = 2y + 3 ;
x + y = 12 .
____________________________
→ y = 12 − x ;
_____________________________
Substitute "(12−x)" for "y" in the equation:
" x = 2y + 3 " ;
→ x = 2(12 − x) + 3 ;
_____________________________________
Note the "distributive property of multiplication" :
_____________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
_____________________________________
As such:
_____________________________________
→ 2(12 − x) = 2(12) − 2(x) = 24 − 2x ;
_____________________________________
So; rewrite:
_____________________________________
x = 2(12 − x) + 3 ;
as:
_____________________________________
→ x = 24 − 2x + 3 ;
→ x = 27 − 2x ;
Add "2x" to each side of the equation:
→ x + 2x = 27 − 2x + 2x ;
→ 3x = 27 ;
Divide each side of the equation by "3" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
3x / 3 = 27 / 3 ;
x = 9 .
___________________________
Note: "y = 12 − x" ; Substitute "9" for "x" ; to solve for "y" ;
→ y = 12 − 9 = 3 ;
→ y = 3 .
__________________________
So, x = 9 ; and y = 3.
____________________________
The numbers are: "3" and "9" .
_____________________________
To check our answers:
Let us plug these numbers into the original equations;

Ron works 5 hours for a total of $300. He deposits all of his money in his account. He is trying to save a $500 for a new LED TV. How many hours must he work to ake home $500, if he saves all of his earnings
Answers
Ron's hourly wage is $60. To save $500 for a new LED TV, he needs to work approximately 8.3 hours. Rounding up, he should work 9 hours to earn the required amount.
Ron earns $300 for working 5 hours, which means his hourly wage is $300 / 5 hours = $60 per hour. To save up for a $500 LED TV, Ron needs to determine how many hours he must work to earn that amount.
To calculate the total hours Ron needs to work to save $500, we divide the total amount he wants to save by his hourly wage:
$500 ÷ $60 per hour = 8.3 hours
Therefore, Ron needs to work approximately 8.3 hours to earn $500, assuming he continues to save all of his earnings. In practice, since he cannot work a fraction of the hour, Ron would need to round up to the nearest whole hour, meaning he needs to work 9 hours to meet or exceed his savings goal.

The area of the conference table in Mr. Nathan’s office must be no more than 175 ft2. If the length of the table is 18 ft more than the width, x, which interval can be the possible widths?
Answers
First, we know that width = x
Which means that length = x +18
So, the possible equation for the Table's area is
X (X + 18) ≤ 175
X^2 + 18x - 175 ≤ 0
Next, we need to calculate is by using complete square method
x^2 + 18x + 81 ≤ 175 + 81
(x + 9)^2 ≤ 256
|x + 9| ≤ sqrt(256)
|x + 9| ≤ +-16
-16 ≤ x + 9 ≤ 16
-16 - 9 ≤ x ≤ 16 - 9
-25 ≤ x ≤ 7
Since the width couldn't be negative, we can change -25 with 0,
so it become
0 < x ≤ 7
