i think of a number, multiply it by 3 and add 4 and i get 22
form an equation, using x for the unknown number and then solve it
The student's clues form the equation 3x + 4 = 22. When solved, this equation reveals that the original number x is 6.
Explanation:The student is creating an algebraic equation to find an unknown number. Starting with the clues given:
They think of a number (which we represent with x)Multiply the number by 3 (3x)Add 4 (3x + 4)The result is 22 (3x + 4 = 22)Now, we can solve this equation to find x:
Start by subtracting 4 from both sides of the equation (3x + 4 - 4 = 22 - 4)Simplify to get 3x = 18Then divide both sides by 3 (x = 18/3)This gives us x = 6 as the unknown numberLearn more about Algebra here:https://brainly.com/question/24875240

-3x-4y-3z=-7
2x-6y+2z=3
5x-2y+5z=9
Answer:
Given equations have no solution
Step-by-step explanation:
Given -
Three set of equations -
[tex]-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9[/tex]
We will now equate "x" in the first equation in terms of "y" and "Z" and put it in second equation -
[tex]-3x-4y-3z=-7\\x = \frac{1}{3} (-4y -3z+7)\\\frac{2}{3}(-4y -3z+7) -6y+2z=3\\-8.667 y = -1.667\\y = 0.192\\[/tex]
We will substitute the value of y in the under given equation-
[tex]x = \frac{1}{3} (-4y -3z+7)\\x = \frac{1}{3} (-4*0.192 -3z+7)\\x= 2.077-z[/tex]
substituting the derived values in last equation, we get -
[tex]5x-2y+5z=9\\5(2.077-z)-2(0.192)+5z=9\\10.385-5z-0.384+5z=9\\0=-1[/tex]
Hence, the given equations have no solution

Give an example of a linear equation perpendicular to y=5
Final answer:
A linear equation perpendicular to y=5 is a vertical line, expressed as x=c, where c is any real number. For instance, x=2 is perpendicular to y=5.
Explanation:
A linear equation perpendicular to y=5 would need to have an undefined slope, meaning it's a vertical line. Since y=5 is a horizontal line, a perpendicular line will have no slope value that we can put in terms of y=mx+b, where m represents the slope and b represents the y-intercept. Thus, the equation will be of the form x=c, where c is any real number. This represents a vertical line that crosses the x-axis at the point (c,0).
For example, the linear equation x=2 is perpendicular to y=5 and crosses the x-axis at the point (2,0).
Chad owns twice as many cds as carlin owns. if you add 6 to the number of cds chad owns and then divide by 7, you get the number of cds bryce owns. bryce owns 30 cds. how many cds does carlin own?
An equation is formed of two equal expressions. The number of CDs owned by Carlin is 102.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the following points:
Chad owns twice as many CDs as Carlin owns. if you add 6 to the number of CDs chad owns and then divide by 7, you get the number of CDs Bryce owns. Bryce owns 30 CDs.Let the variables represent the following numbers as shown,
CDs owned by Chad = M.Cds owned by Carlin = NCDs owned by Bryce = OThe number of CDs owned by Chad.
M = 2N ______(1)
The number of CDs owned by Carlin.
= N ________(2)
The number of CDs owned by Bryce.
O = (6+2N) / 7
And O = 30
30 = (6 + 2N) / 7 ________(3)
From (3), the value of N can be written as,
30 = (6 + 2N) / 7
Multiply both sides by 7
30 x 7 = 6 + 2N
210 = 6 + 2N
Subtract 6 on both sides.
210 - 6 = 6 + 2N - 6
204 = 2N
Divide both sides by 2.
102 = N
N = 102
Thus, the number of CDs owned by Carlin is 102.

What is the equation of the line that is parallel to the line 5x+2y=12 and passes through the point (-2, 4)?
The equation of the line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4) is given as [tex]\(y = -\frac{5}{2}x - 1\).[/tex]
To find the equation of a line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4), we need to follow these steps:
1. Convert the given equation[tex]\(5x + 2y = 12\)[/tex] into slope-intercept form [tex]\(y = mx + b\).[/tex]
2. Determine the slope of the given line.
3. Use the slope and the given point to find the equation of the parallel line using the point-slope form.
4. Convert the equation into slope-intercept form if needed.
Let's start with step 1:
1. Convert [tex]\(5x + 2y = 12\)[/tex] into slope-intercept form [tex]\(y = mx + b\):[/tex]
Subtract [tex]\(5x\)[/tex] from both sides:
[tex]\[2y = -5x + 12\][/tex]
Divide both sides by 2:
[tex]\[y = -\frac{5}{2}x + 6\][/tex]
Now, we know that the slope of the given line is [tex]\(-\frac{5}{2}\)[/tex] . Since the line we're looking for is parallel to this line, it will have the same slope.
2. The slope [tex](\(m\))[/tex] of the parallel line is [tex]\(-\frac{5}{2}\).[/tex]
Next, we use the point-slope form[tex]\(y - y_1 = m(x - x_1)\),[/tex]where [tex]\((x_1, y_1)\)[/tex] is the given point (-2, 4) and [tex]\(m\)[/tex] is the slope.
3. Substitute the values into the point-slope form:
[tex]\[y - 4 = -\frac{5}{2}(x - (-2))\][/tex]
[tex]\[y - 4 = -\frac{5}{2}(x + 2)\][/tex]
Now, distribute[tex]\(-\frac{5}{2}\):[/tex]
[tex]\[y - 4 = -\frac{5}{2}x - 5\][/tex]
4. Convert to slope-intercept form:
Add 4 to both sides:
[tex]\[y = -\frac{5}{2}x - 5 + 4\][/tex]
[tex]\[y = -\frac{5}{2}x - 1\][/tex]
So, the equation of the line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4) is [tex]\(y = -\frac{5}{2}x - 1\).[/tex]

*PLEASE HELP* BRAINLIEST* A 10% discount is offered on a certain item that sells for $10.95. How much is the discount and what is the discounted sales price?
Amount of discount =
Discounted sales price =
The amount of discount is $1.095 and the discounted sales price is $9.855.
We need to calculate the amount of discount and then subtract it from the original sales price to find the discounted sales price.
First, we calculate the amount of discount. A 10% discount on an item selling for $10.95 means we need to find 10% of $10.95. To find 10% of a number, we can multiply the number by 0.10 (which is the decimal equivalent of 10%).
Amount of discount = 10% of $10.95
= 0.10 [tex]\times[/tex] $10.95
= $1.095
Now that we have the amount of discount, we can calculate the discounted sales price by subtracting the discount from the original sales price.
Discounted sales price = Original sales price - Amount of discount
= $10.95 - $1.095
= $9.855
