Answer:
x = 9
Step-by-step explanation:
take -6 to the other side so you add it to 30 = 36
equation is now 4x = 36
divide 4/4 and 36/4
x = 9
the solution to the equation 4x - 6 = 30 is x = 9
To solve the equation 4x - 6 = 30 and find the value of x, we can follow these steps:
1. Begin by isolating the term with the variable on one side of the equation. In this case, we want to isolate the 4x term. Add 6 to both sides of the equation:
4x - 6 + 6 = 30 + 6
4x = 36
2. To solve for x, divide both sides of the equation by 4:
(4x) / 4 = 36 / 4
x = 9
Therefore, the solution to the equation 4x - 6 = 30 is x = 9. When we substitute x with 9 in the equation, we have 4(9) - 6, which indeed equals 30. Thus, x = 9 satisfies the equation, and it represents the value that makes the equation true.

HELP ME PLS IM STUCK HELLA AND ITS WRONG WHICH ONES RIGHT
Answer:
It is e = 3
Step-by-step explanation:
It is e = 3 and not e = -3 because 44e - 41 e = 3e, then you'd subtract 30 from both sides to get the 3e equal to something which is 9. then dividing both sides by 3 would give you e = 3

Consider the right triangle below.
6x - 44
2x - 20
3x + 24
If the perimeter of the triangle is 224 cm, find the area of the triangle.
The area of the triangle is
cm
Answer:
Area = 1,344 cm²
Step-by-step explanation:
First, find the value of x and the numerical side length of all sides of the triangle before finding the area.
Thus:
Perimeter of a triangle = sum of all its side
Therefore,
(6x - 44) + (2x - 20) + (3x + 24) = 224
Solve for x
6x - 44 + 2x - 20 + 3x + 24 = 224
Add like terms
11x - 40 = 224
Add 40 to both sides
11x = 224 + 40
11x = 264
Divide both sides by 11
x = 24
Find the measurement of each side length by plugging in the value of x:
Hypotenuse = 6x - 44 = 6(24) - 44 = 100 cm
Height = 2x - 20 = 2(24) - 20 = 28 cm
Base = 3x + 24 = 3(24) + 24 = 96 cm
Find the area:
Area = ½×base×height
Plug in the values
= ½×96×28
Area = 1,344 cm²

If Y (-7,-4) and (5,2), find the slope of a line perpendicular to YZ. Please help if you can
Answer:
-2
Step-by-step explanation:
The slop of YZ is 1/2. The slope perpendicular would be opposite, making it -2.
Answer:
- 2
Step-by-step explanation:
Calculate the slope m of YZ using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = Y(- 7, - 4) and (x₂, y₂ ) = Z(5, 2)
m = [tex]\frac{2+4}{5+7}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2

Please helppp it’s confusing!!!
Answer:
First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))
So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).
So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.
Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3
In short, 3(2^0) = 3
In rectangle ABCD, diagonals AC and BD intersect at E. If AE=3x-28 and DE=.5x+12, find the length of AC.
Given:
In rectangle ABCD, diagonals AC and BD intersect at E, AE=3x-28 and DE=.5x+12.
To find:
The length of AC.
Solution:
We know that, diagonals of a rectangle are equal and they bisect each other.
In rectangle ABCD, diagonals AC and BD intersect at E, so
[tex]AE=BE=CE=DE[/tex] ...(i)
Taking [tex]AE=DE[/tex], we get
[tex]3x-28=0.5x+12[/tex]
[tex]3x-0.5x=28+12[/tex]
[tex]2.5x=40[/tex]
Divide both sides by 2.5.
[tex]x=\dfrac{40}{2.5}[/tex]
[tex]x=16[/tex]
Now,
[tex]AE=3x-28[/tex]
[tex]AE=3(16)-28[/tex]
[tex]AE=48-28[/tex]
[tex]AE=20[/tex]
Using segment addition property,
[tex]AC=AE+CE[/tex]
[tex]AC=AE+AE[/tex] [Using (i)]
[tex]AC=20+20[/tex]
[tex]AC=40[/tex]
Therefore, the length of AC is 40 units.

Your class is selling chocolates and caramel corn. Boxes of
chocolate sell for $6 each and bags of caramel corn sell for
$5 each. A total of 535 items were sold and $2889 was
raised. How many of each item was sold?

o 214 boxes of chocolate, 321 bags of caramel corn
O 343 boxes of chocolate, 192 bags of caramel corn
0 211 boxes of chocolate, 324 bags of caramel corn
214 boxes of chocolate, 321 bags of caramel corn item was sold.
How many of each item was sold?Boxes of chocolate sell for $6 each and bags of caramel corn sell for
$5 each. A total of 535 items were sold and $2889 was
raised.
set of of chocolate was sold x boxes,
because a total of 535 items more sold .
so the caramel corn was sold (535 -x) bags,
and boxes of chocolate sell for $6 each , bags of caramel corn for each and $2889 was raised.
so 6 x+ 5.(535-x) = $2889.
6 x+ 5.535-x = $2889.
6 x+ 2675 - 5x = $2889.
6x - 5x =2889-265
x =214
so the caramel corn was sold 535-x =535-214 = 321

Caramel corn bags cost $5 apiece, while chocolate boxes cost $6 each. 535 products in total were sold, bringing in a total of $2889 then there exists 214 boxes of chocolate, 321 bags of caramel corn was sold.
How to estimate the value of x?Any one of the forms, including addition, subtraction, multiplication, and division, should be used for the algebraic expression. Bring the variable to the left side and the other values to the right side in order to find the value of x. To find the answer, simplify the values.
Let set of of chocolate was sold x boxes,
because a total of 535 items more sold .
so the caramel corn was sold (535 - x) bags, and boxes of chocolate sell for $6 each , bags of caramel corn for each and $2889 was raised.
From the given information, we get
6x + 5(535 - x) = $2889
simplifying the above equation, we get
6x + 5 × 535 - 5x = $2889
6x + 2675 - 5x = $2889
6x - 5x = 2889 - 265
x = 214
So the caramel corn was sold = 535 - x
Substitute the value of x in the above equation, we get
= 535 - 214
= 321
There exists 214 boxes of chocolate, 321 bags of caramel corn was sold.
Therefore, the correct answer is option b) 214 boxes of chocolate, 321 bags of caramel corn.
