2x +4 (3 - 2x) = 3(2x + 2)/6 + 4
from my math book
Answer:
x = 1
Step-by-step explanation:
2x +4 (3 - 2x) = 3(2x + 2)/6 + 4
2x+12-8x = (6x+6)/6 +4
-6x + 12 = x+1+4
12-5 = 7x
7x = 7
x=1
Hope this helps!
2x + 4(3-2x) = 3(2x+2)/6 +4
Break the brackets :
2x + 12 - 8x = (6x+6)/6 + 4
2x + 12 - 8x = x + 5
2x + 12 - 8x - (x+5) = 0
2x + 12 - 8x - x - 5 = 0
-7x + 7 = 0
-7x = -7
x = 1.
Hope it helps :)
What value of x will make these two expression equivalent?
-3/7 and x/21
A X=-3 B x=7 Cx=9 Dx=-9
Answer:
D. x = -9
Step-by-step explanation:
We want -(3/7) = (x/21)
Cross multiply: 7x = - 63
x = - 9
Check:
Does (-9/21) = -(3/7)?
(-9/21) reduces to -(3/7) YES

The dimensions, in centimetres, of this rectangle are shown as algebraic expressions.
Not to scale
5x-y-8
3x + y-4
2x-6-3
3x + 5y +4
Work out the length and width of the rectangle.
Answer:
length = 15
Width = 9
Step-by-step explanation:
In a rectangle opposite sides are equal.
5x - y- 8 =3x +5y + 4
5x - 3x -y - 5y = 4 + 8
2x - 6y = 12
Divide the entire equation by 2
x - 3y = 6 --------------(I)
3x + y - 4 = 2x - 6y - 3
3x - 2x + y + 6y = -3 + 4
x + 7y = 1 -------------(II)
Multiply equation (II) by (-1)
(I) x - 3y = 6
(II)*(-1) -x - 7y = -1 {Now add. 'x' will be eliminated}
-10y= 5
y = 5/(-10)
y = -0.5
Plugin y = -0.5 in equation (I)
x - 3*(-0.5) = 6
x + 1.5 = 6
x = 6 - 1.5
x = 4.5
Length = 5x - y - 8
= 5*4.5 - (-0.5) - 8
= 22.5 + 0.5 - 8
= 23 - 8
Length = 15
Width = 2x - 6y - 3
= 2*4.5 - 6*(-0.5) - 3
= 9 + 3 - 3
Width = 9

The altitude of the base of a cloud
formation is called the ceiling. To find the ceiling
one night, a meteorologist directed a spotlight
vertically at the clouds. Using a theodolite placed
83 meters from the spotlight and 1. 5 meters above
the ground, he found the angle of elevation to be
62. 7º. How high was the ceiling?
The height of the ceiling is 162.31 meters
The situation will form a right angle triangle.
Right angle triangle:Right triangle has one of its angles as 90 degree. Therefore, the sides can be found using trigonometric ratios
The triangle formed, the theodolite distance from the spotlight is the adjacent side. Therefore,
tan 62.7 = opposite / adjacent
tan 62.7 = x / 83
cross multiply
x = 83 × tan 62.7
x = 160.809554025 m
Therefore, the height of the ceiling form the ground is as follows:
160.809554025 + 1.5 = 162.309554025 mlearn more on right angle triangle here; https://brainly.com/question/13481976
Jimmy can run 7.5 miles in 30 min. If he keeps this constant rate, how many hours will it take him to run 150 miles?
Answer:
10 hours
Step-by-step explanation:
1. Create a chart.
miles - hours
7.5. - 0.5 (30 minutes = 0.5 hours)
150. - x (let's use a variable to represent number of hours Jimmy ran)
2. Cross multiply:
7.5(x) = 150(0.5)
7.5x. = 75
3. To isolate x, divide both sides of equation by 7.5
7.5x/7.5 = 75/7.5
4. 7.5 crosses out with itself on the left side of the equation.
5. 75/7.5 = 10
x = 10
Therefore, Jimmy ran 150 miles in ten hours.
Explain why the binomial n2 - 16 is not equal to (n + 8)(n - 8). please helppp due in 10 minutesss
Answer:
see explanation
Step-by-step explanation:
n² - 16 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b) , then
n² - 16
= n² - 4²
= (n + 4)(n - 4)
cannot be (n + 8)(n - 8)
= n² - 64
Answer/Step-by-step explanation:
Let's first solve [tex](n+8)(n-8)[/tex]
Distribute
[tex]n(n-8)+8(n-8)[/tex]
Distribute
[tex]n^2-8n+8(n-8)[/tex]
Distribute
[tex]n^2-8n+64[/tex]
Combine like terms
[tex]n^2-64[/tex]
Therefore n2-16 is not equal to (n+8)(n-8) because (n+8)(n-8) is equal to n^2-64.

The soccer net in Peter's back yard is 5 1/2 feet high, but only 4 feet wide. Jill's soccer net is also 5 1/2 feet high, but is 12 feet wide How many times larger is the area of Jills soccer net? Explain your solution.
The area of Jill's soccer net is 3 times larger than area of Peter's soccer net.
Area of Peter's soccer net
The area of Peter's soccer net is determined by using area of rectangle as shown below;
A1 = 5.5 ft x 4 ft
A1 = 22 ft²
Area of Jill's soccer netA2 = 5.5 ft x 12 ft
A2 = 66 ft²
Ratio of the area of their soccer netA2/A1 = 66/22
A2/A1 = 3
Thus, the area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

all of my faces are congruent.
I have 8 vertices
I am a 3D figure
what am I?
All the faces are the same and 8 vertices would make a cube.
Answer: cube
All of its faces are congruent, it has 8 vertices and it is a 3D figure, so it is a cube.
A cube is a three-dimensional geometric shape that meets the given criteria.
Let's break down the reasons why:
All Faces Congruent: In a cube, all six faces are congruent to each other.This means that each face has the same shape and size, and all angles within the cube are right angles (90 degrees).
8 Vertices: A cube has 8 vertices (corners).Each vertex is the point where three edges of the cube meet.
3D Figure: A cube is a three-dimensional object.It has length, width, and height, making it a 3D geometric figure.
A cube is a special type of rectangular prism where all sides are equal in length.
Its symmetry and regularity in terms of congruent faces, edges, and vertices make it a fundamental and easily recognizable three-dimensional shape.

Factor completely x2 − 10x 25. (x − 5)(x − 5) (x 5)(x 5) (x 5)(x − 5) (x − 25)(x − 1).
Answer:
[tex](x-5)(x-5)[/tex]
Step-by-step explanation:
We need to find two numbers that multiply to get 25 and have a sum of -10...
(-5)(-5)=25
-5-5=-10
We can split -10x into -5x and -5x:
[tex]x^2-5x-5x+25[/tex]
Factor each half of the expression separately:
[tex]x(x-5)-5(x-5)[/tex]
Since both x and -5 are being multiplied by (x-5), we can combine them to get:
[tex](x-5)(x-5)[/tex]
