This linear equation3(x+4)-2=16
9514 1404 393
Answer:
x = 2
Step-by-step explanation:
This linear equation has 1 answer. It can be found by working backward through the operations that are performed on the variable. Those are ...
4 is addedthe sum is multiplied by 3the product has 2 subtractedWe can "undo" the last of these by adding 2 to both sides of the equation.
3(x +4) = 18
Undo the multiplication by 3 by dividing both sides by 3.
x +4 = 6
Undo the addition of 4 by adding -4.
x = 2 . . . . . the solution
__
Check
Put 2 in the equation where x is and see if it is true.
3(2 +4) -2 = 16
3(6) -2 = 16
18 -2 = 16 . . . . . true
Which of the equations below have one solution? Select all that apply. 8x–3x+5=5x–2 9=3(5x–2) 6x–(3x+8)=16 9x+4–x=4(2x+1)
Answer:
The equations that have one solution are 9=3(5x–2) and 6x–(3x+8)=16
Step-by-step explanation:
To determine which equations have one solution, we will determine the solution(s) to all the equations (that is, find the value of the unknown, x).
1. 8x–3x+5=5x–2
This becomes
5x+5=5x-2
Subtract 5x from both sides
5x-5x+5 = 5x-5x-2
0+5 = 0-2
This equation has no solution
2. 9=3(5x–2)
First, open the bracket by distributing 3
∴ 9 = 15x - 6
Then, add 6 to both sides
9+6 = 15x -6 +6
15 = 15x
Divide both sides by 15
15/15 = 15x/15
1 = x
∴ x = 1
This has one solution.
3. 6x–(3x+8)=16
Open the bracket by distributing –1
6x -3x -8 = 16
3x - 8 = 16
Add 8 to both sides
3x -8 +8 = 16 + 8
3x = 24
Divide both sides by 3
3x/3 = 24/3
x = 8
This has one solution.
4. 9x+4–x=4(2x+1)
This becomes
9x -x +4 = 4(2x+1)
Then, 8x +4 = 4(2x+1)
Open the bracket by distributing 4
8x +4 = 8x +4
This is true for any value of x.
Hence, the equations that have one solution are 9=3(5x–2) and 6x–(3x+8)=16.

What is the value of x?
Enter your answer in the box.
x =
Answer:
x = 4
Step-by-step explanation:
Using the sine ratio in right Δ JKL and exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JL}{KL}[/tex] = [tex]\frac{JL}{8\sqrt{2} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2JL = 8[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
JL = 4[tex]\sqrt{2}[/tex]
---------------------------------------------------------------
Using the sine ratio in Δ JLM and exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{ML}{JL}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
x × [tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
x = 4
Answer:
4
Step-by-step explanation:
When explaining my solution I will assume that you know SOH CAH TOA. If you don't leave a comment below and I will explain it
We know the line KL and angle K which is enough to get the rest of the lenghts of this triangle
Using CAH we have
Cos30=x/8sqrt2
solve for x and get
8sqrt2Cos30=x
Put this into your calculator and get that line KJ= 9.7979
With this we can solve for the rest of the trinagle using a^2+b^2=c^2
So we have
9.7979^2+LJ^2=(8sqrt2)^2
Compute what you can and get x by itself to get
LJ^2=32
LJ=sqrt32 which is 5.6568
Now that we know the length of line LJ we can solve the second part of the triange.
Knowing that the hypotonous is equal to 5.6568 and angle j=45 we can use SOH
we have
sin45=x/5.6568
Solve this and get
5.6568sin45=4
x=4

Tell whether the ratios form a proportion.
1 to 3 and 7 to 21
Answer:
yes they form a proportion
Step-by-step explanation:
1 to 3 and 7 to 21 are equal
we can check this by multiplying each number in the 1 to 3 ratio by 7 to make it equal with the other ratio, 7 to 21.

Answer:
B) -1/2
C) {30, 150}
Step-by-step explanation:
Question 3)
We can see that the angle equals 210* which equals 7pi/6 (in radians)
The coordinates would be [tex](\frac{-\sqrt{3} }{2}, \frac{-1}{2})[/tex]
Since the problem is asking for sinθ, we will use -1/2 (the y-coordinate)
So the answer is B) -1/2..
Question 4)
If the criteria of the answer is that it must be between 0 < θ < 360 and it must have a y-value of 1/2 in its coordinate (sinθ = 1/2), then we will choose angles that meet this criteria. When we look at the unit circle (see the attached) we can see that only the angles of 30* and 150* match this answer, so our answer is c.

Find the area of the
regular figure below:
A) 466 mm2
B) 430 mm2
C) 404 mm2
D) 495 mm2
E) 512 mm2
explain pls
Answer:
Option A
Step-by-step explanation:
Central angle of the pentagon = [tex]\frac{360}{\text{Number of sides of the regular polygon}}[/tex]
= [tex]\frac{360}{5}[/tex]
= 72°
Measure of ∠BAC = 72°
Therefore, measure of ∠BAD = [tex]\frac{72}{2}[/tex]
= 36°
By sine rule in ΔABD,
sin(36°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BD}{AB}[/tex]
= [tex]\frac{BD}{14}[/tex]
BD = 14(sin36°)
= 8.23 mm
Similarly, by cosine rule,
cos(36°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AD}{AB}[/tex]
= [tex]\frac{AD}{14}[/tex]
AD = 14(cos36°)
= 11.33 mm
Area of ΔABC = 2(Area of ΔABD)
= [tex]2(\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= AD × BD
= 11.33 × 8.23
= 93.21 mm²
Since, area of regular pentagon given in the picture = 5(area of ΔABC)
= 5(93.21)
= 466 mm²
Therefore, Option A will be the answer.

The area of circular garden is 706.5 feet2. What is the circumference of the garden? (Use 3.14 for pi .)
Answer:
30[tex]\pi[/tex] or 94.2 feet
Step-by-step explanation:
Use the area formula to find the radius:
A = [tex]\pi[/tex]r²
706.5 = 3.14r²
225 = r²
15 = r
Then, find the circumference using the formula:
C = 2[tex]\pi[/tex]r
C = 2[tex]\pi[/tex](15)
C = 30[tex]\pi[/tex]
So, the circumference of the garden is 30[tex]\pi[/tex] or approximately 94.2 feet
