Answer:
The solution of the equation [tex]3 + x = 11[/tex] is [tex]x = 8[/tex].
Step-by-step explanation:
Let [tex]3 + x = 11[/tex], we see that number of equation and variables are both the same and can be solved by algebraic means.
1) [tex]3 + x = 11[/tex] Given
2) [tex]x + 3 = 11[/tex] Commutative property
3) [tex]x + [3+(-3)] = 11 + (-3)[/tex] Compatibility with addition/Associative property
4) [tex]x = 8[/tex] Additive inverse/Modulative property/Definition of substraction/Result
The solution of the equation [tex]3 + x = 11[/tex] is [tex]x = 8[/tex].

Alexis wrote 28 - 8 = 20. Then she
wrote 28 -8 + 9 = 20 – 9. Are her
equations balanced? Explain.
Answer:
no this is because 28-8+9=29 and 20-9=11
Step-by-step explanation:
Answer:
Her equation is not balanced.
Because 28 - 8 + 9 = 20 - 9
29 = 11 ( its not balanced)
She put the same symbol or sign on both side.Here she put different sign on both side .so this equation is not balanced.

Which equation can be used to solve for x in the following diagram?
7xº
11x°
Answer:
7x° + 11x° = 90°
(Required equation)
Step-by-step explanation:
7x° + 11x° = 90°
(complementary angles)
18x° = 90°
18x = 90
x = 90/18
x = 5

Write down the value of angle y, giving a reason for your answer
Y=
Other angle given is 67 degrees
Answer:
y would be 67 as well.
Step-by-step explanation:
they are alternate interior angles. hope it helps
In part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
Part(a)
We have a triangle shown in the picture.
The two lengths of a triangle are equal.
The angle opposite to the sides will be equal.
As we know,
The triangle's interior angles add up to 180°.
180 = 55 + 55 + x
x = 180 - 110
x = 70 degrees
In part (b)
There are two parallel lines shown in the picture.
The angle y will be the same as 67 degrees because two parallel lines are cut by a transversal line.
Thus, in the part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.

please mark me as brainlist as brainlist
Answer:
[tex]\frac{7}{8}[/tex]
Step-by-step explanation:
Find the average by adding the 2 fractions and dividing the sum by 2
[tex]\frac{1}{2}[/tex] + 1 [tex]\frac{1}{4}[/tex]
= [tex]\frac{1}{2}[/tex] + [tex]\frac{5}{4}[/tex]
= [tex]\frac{2}{4}[/tex] + [tex]\frac{5}{4}[/tex]
= [tex]\frac{7}{4}[/tex]
Then
[tex]\frac{7}{4}[/tex] ÷ 2
= [tex]\frac{7}{4}[/tex] × [tex]\frac{1}{2}[/tex]
= [tex]\frac{7}{8}[/tex]

reflection and translation.
Given:
The different transformation in the options.
To find:
The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.
Solution:
In option 1,
[tex](x,y)\to (y,x)[/tex]
It represents reflection across the line y=x.
In option 2,
[tex](x,y)\to (x,-y)[/tex]
It represents reflection across the x-axis.
In option 3,
[tex](x,y)\to (4x,4y)[/tex]
It represents dilation by scale factor 4 and the center of dilation is at origin.
In option 4,
[tex](x,y)\to (x+2,y-5)[/tex]
It represents translation 2 units right and 5 units down.
We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.
So, the perimeter of the figure and its image are same in the case of reflection and translation.
But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.
Therefore, the correct option is 3.
If BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6, what are the values of x and AC?
Answer: x=7 and AC = 44 unuts.
Step-by-step explanation:
We know that the diagonals of a parallelogram bisect each other. (i)
Here in parallelogram ABCD , AC and Bd are diagonals intersecting at E.
BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6
Using (i)
[tex]BE=\dfrac{BD}{2}\\\\2x+2=\dfrac{5x-3}{2}\\\\ 2(2x+2)=5x-3\\\\ 4x+4= 5x-3\\\\ 5x-4x=4+3\\\\ x= 7[/tex]
Now , AE = 4(7)-6 = 28-6 = 22
AC =2 AE = 2 (22) =44 units.
Hence, x=7 and AC = 44 unuts.
Drag each angle measure to the correct location on the image. Not all angle measures will be used.
Determine the measures of the angles.

Step-by-step explanation:
Answer:
12 - 4x
Step-by-step explanation:
Distribute the 4 to both terms within the parentheses:
4(3 - x)
4*3 - 4*x
12 - 4x
This is called the expanded form, while 4(3 - x) is called the factored form of this expression.

Perimeter of rectangle = 52 cm
2*(length + width) = 52
2*(l + 42/5) = 52
[tex]l +\frac{42}{5}=\frac{52}{2}\\\\l+\frac{42}{5}=26\\\\ l = 26 - \frac{42}{5}\\\\ l = \frac{26*5}{1*5}-\frac{42}{5}\\\\l = \frac{130}{5}-\frac{42}{5}\\\\l=\frac{130-42}{5}\\l= \frac{88}{5}\\\\[/tex]

Problem: A pole is being held up with a 10 meter rope. The cable is making a 42° of elevation from the ground to
the top of the pole. What is the distance from the base of the pole to the base of the rope ? Round your answer
to the nearest tenth of a meter.
Answer:
x = 7.4
Step-by-step explanation:
cos(42°) = x/10 or distance from bases / rope length
Using the calculator find the value of cos(42°):
cos(42°) = 0.74 = x/10
Find x using the value of cos(42°):
x/10 = 0.74
x = 7.4
