X+24=35 how to solve this
Answer:
X = 11
Step-by-step explanation:
Simplifying
X + 24 = 35
Reorder the terms:
24 + X = 35
Solving
24 + X = 35
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-24' to each side of the equation.
24 + -24 + X = 35 + -24
Combine like terms: 24 + -24 = 0
0 + X = 35 + -24
X = 35 + -24
Combine like terms: 35 + -24 = 11
X = 11
Simplifying
X = 11
Answer:
x+24=35
then collect like terms together, which means "x" terms in one side and numbers in one side:
x=35-(+24)
we need to change the signs when ever we change its place, like changing from one side to another

Step-by-step explanation:
After subtracting the width of the picture from the width of the wall, we find the length of the space to be ...
14 5/6 - 1 1/2 = (14 -1) +(5/6 -3/6) = 13 2/6 . . . feet
Dividing that space in half gives ...
(13 2/6)/2 = (13/2) +(2/6)/2
= 6 1/2 +1/6 = 6 3/6 + 1/6
= 6 4/6 = 6 2/3 . . . . feet
The space on either side of the picture is 6 2/3 feet.
If my final is worth 15% of my mark and I'm at 70% right now what would I need to get on my final to get at least 75% overall
Answer:
Step-by-step explanation:
70*85/100 = 59.5 This is what you have right now.
You need 15.5 gross marks to get up to 75
As you can see, I'm sorry to say, you cannot do it.
Mind you, you would not miss by much. You could get about 74.5 if you got a hundred % on your final. This is just an estimate. I'm just trying to show you what you have to do to get near your goal. The 59.5 is accurate. So is the 15.5. Only your possible final grade is an estimate.

Henry would pay less for the tablet on the website.
Step-by-step explanation:
Given :
Regular price = $829
On website :
80% discount off the regular price :
(100 - 80)% * regular price
20% * 829
0.2 * $829 = $165.8
At store :
70% off regular price :
(100 - 70)% * 829
0.3 * 829
= $248.7
10% off sale price :
(100 - 10)% * $248.7
0.9 * 248.7
= $223.83
Henry would pay less for the tablet on the website.

The area of a rectangle is 3x2 - 12x square yards. If the width is 3x yards, what is the length of the rectangle?
Answer:
x - 4 yards.
Step-by-step explanation:
Given:
Area of rectangle = 3x^2 - 12x square yards
Width = 3x yards
To find:
Length of rectangle
Solution:
The area of a rectangle is equal to the product of its length and width.
Area of rectangle = Length * Width
Substituting the given values, we get:
3x^2 - 12x = Length * 3x
Length =( 3x^2 - 12x )3x
Length = x-4
Therefore, the length of the rectangle is x - 4 yards.
Answer: The length of the rectangle is x - 4 yards.
Step-by-step explanation:
We can create an equation to solve this word problem, where the variable L = length.
3x × L = \(3x^2 - 12x\)
We need to solve for the variable L, to find the length of the rectangle.
First lets factor the right side of the equation to make it easier to divide with.
3x × L = \(3x^2 - 12x\)
We can factor out 3x from the right side of the equation.
3x × L = 3x(x - 4)
Now we need to get the variable L by itself (isolating the variable). In order to do that, we can divide both sides by 3x.
3x × L = 3x(x - 4)
/3x /3x
L = x - 4
The length of the rectangle is x - 4 yards.

The arrow is at a height of 48 ft after approx. ___ s and after ___ s.
The arrow is at a height of 48 ft after approx. 3 - √6 s and after 3 + √6 s.
To find the time it takes for the arrow to reach a height of 48 ft, we can use the formula for the height of the arrow:
s = v0t - 16t^2
Here, s represents the height of the arrow, v0 is the initial velocity, and t is the time.
Given that the initial velocity, v0, is 96 ft/s and the height, s, is 48 ft, we can set up the equation:
48 = 96t - 16t^2
Now, let's solve this equation to find the time it takes for the arrow to reach a height of 48 ft.
Rearranging the equation:
16t^2 - 96t + 48 = 0
Dividing the equation by 16 to simplify:
t^2 - 6*t + 3 = 0
We now have a quadratic equation in the form of at^2 + bt + c = 0, where a = 1, b = -6, and c = 3.
Using the quadratic formula:
t = (-b ± √(b^2 - 4ac)) / (2a)
Plugging in the values:
t = (6 ± √((-6)^2 - 413)) / (2*1)
t = (6 ± √(36 - 12)) / 2
t = (6 ± √24) / 2
Simplifying the square root:
t = (6 ± 2√6) / 2
t = 3 ± √6
Therefore, the arrow reaches a height of 48 ft after approximately 3 + √6 seconds and 3 - √6 seconds.
In summary, the arrow takes approximately 3 + √6 seconds and 3 - √6 seconds to reach a height of 48 ft, assuming an initial velocity of 96 ft/s.

In the 2002 - 2003 NBA regular season, the Sacramento Kings
won 13 more than twice as many games as they lost, The Kings
played 82 games. How many wins and losses did the team
mave?
Answer: Number of games lost = 23 and Number of games won = 59.
Step-by-step explanation:
Let x = Number of games lost, y = Number of games won.
y = 13 + 2x (i)
x+ y = 82 (ii)
Substitute value of y from (i) in (ii) , we get
x+ 13 + 2x = 82
⇒ 3x= 82-13
⇒ 3x = 69
⇒ x= 23 [Divide both sides by 3]
Put value of x in (i), y= 13+2(23) = 13+46=59
Hence, Number of games lost = 23 and Number of games won = 59.

Hello! I am in need of help! For the following problem I need to figure out (1.) IF THE LIMIT EXISTS, (2.) IF IT INDICATES THE EXISTENCE OF HORIZONTAL OR VERTICAL ASYMPTOTES, (3.) GIVE THE EQUATION OF SAID ASYMPTOTE, (4.) IF IT APPROACHES NEGATIVE OR POSITIVE INFINTY FROM THE LEFT AND RIGHT. I would HIGHLY appreciate any help! (This is a Calculus problem by the way)
Given the limit expression:
\(\lim _{x\to\infty}\frac{x^2+5x+6}{2x^2+7x+3}\)Factor both the numerator and denominator:
\(\begin{gathered} x^2+5x+6=(x+2)(x+3) \\ 2x^2+7x+3=(2x+1)(x+3) \end{gathered}\)so,
\(\lim _{x\to\infty}\frac{x^2+5x+6}{2x^2+7x+3}=\lim _{x\to\infty}\frac{(x+2)(x+3)}{(2x+1)(x+3)}=\lim _{x\rightarrow\infty}\frac{x+2}{2x+1}\)Now, divide the numerator and denominator by x:
\(\lim _{x\rightarrow\infty}\frac{x+2}{2x+1}=\lim _{x\rightarrow\infty}\frac{1+\frac{2}{x}}{2+\frac{1}{x}}=\frac{1+0}{2+0}=\frac{1}{2}\)So, the answer is the value of the limit = 1/2
The answer indicates the horizontal asymptote
what would be the equation of said horizontal asymptote?
It will be: y = 1/2
The zeros of the denominator when 2x + 1 = 0
x = -1/2
At this point, the limit approaches to infinity from the right and the left
From the right, it will be positive infinity
From the left, it will be negative infinity

Miss Rose went shopping with 120 she spent 78. What percentage of her money did she spend
Miss Rose spent 65 percentage of her money.
Define percentagePercentage is a way of expressing a fraction or a proportion as a fraction of 100. It is a number or ratio expressed as a fraction of 100, denoted by the symbol "%".
To find the percentage of Miss Rose's money that she spent, we can use the formula:
percentage = (part/whole) x 100
where "part" is the amount she spent, and "whole" is the initial amount of money she had.
In this case, Miss Rose had 120 and spent 78, so the percentage of her money that she spent is:
percentage = (78/120) x 100 = 65
Therefore, Miss Rose spent 65% of her money.

a =14.6 rounded to 1 DP
b= 3.25 rounded to 2 DP
Find the maximum of a - b
Answer:
11.405
Step-by-step explanation:
When rounding numbers, check the digit to the right of the one you're rounding to:
If it is 0, 1, 2, 3 or 4 round downIf it is 5, 6, 7, 8 or 9 round upIf a = 14.6 is rounded to 1 decimal place then:
minimum value of a = 14.55 (rounds up to 14.6)maximum value of a = 14.649999... (rounds down to 14.6)If b = 3.25 is rounded to 2 decimal places then:
minimum value of b = 3.245 (rounds up to 3.25)maximum value of b = 3.2549999... (rounds down to 3.25)Therefore, to find the maximum value of a - b, subtract the smallest value of b from the largest value of a:
\(\implies \sf a_{max}-b_{min}=14.649999...-3.245=11.405\)
Explain why the ratio 3 feet 1 yard has a value of one.
This ratio is using different measures (feet and yard), so the first step is converting yard to feet. The conversion rate is:
1 yard = 3 feet.
So we have that:
\(\frac{3\text{ feet}}{1\text{ yard}}=\frac{3\text{ feet}}{3\text{ feet}}\)The numerator and denominator of the ratio are the same, so the ratio is equivalent to 1.
\(\frac{3\text{ feet}}{3\text{ feet}}=1\)
