Answer:
[tex] \large \boxed{x = \frac{2}{3} }[/tex]
Step-by-step explanation:
Goal
Solve the equation for x-term.Given
Equation[tex] \large{16 - 4(x + 3) = 2x}[/tex]
Step 1
Distribute/Expand 4 in the expression.[tex]16 - 4x - 12 = 2x[/tex]
Step 2
Isolate x and combine like terms.[tex]16 - 12 = 2x + 4x[/tex]
Step 3
Solve the equation for x-term[tex]4 = 6x \\ \frac{4}{6} = x \\ \frac{2}{3} = x[/tex]
Step 4
If you are not sure that the answer is correct, I suggest to check the answer by substituting the value of x in the equation.[tex]16 - 4x - 12 = 2x[/tex]
Substitute x = 2/3 in the equation.
[tex]16 - 4( \frac{2}{3} ) - 12 = 2 (\frac{2}{3} ) \\ 4 -4( \frac{2}{3} ) = 2( \frac{2}{3} )[/tex]
Evaluate
[tex]4 - \frac{8}{3} = \frac{4}{3} [/tex]
Move -8/3 to add with 4/3.
[tex]4 = \frac{4}{3} + \frac{8}{3} \\ 4 = \frac{12}{3} \\ 4 = 4[/tex]
The equation is true for x = 2/3. Hence, the solution is x = 2/3.
Hope this helps! Any questions about the answer can be asked in comments.

Step-by-step explanation:
Parameter is the sum of the lengths of all sides of a polygon. The sides of the polygon are PT, TS, SR, RQ, and QP. To get the length of a side, we use the distance formula: Each vertex in the polygon has its corresponding points:\
So to get the length of side PT, we use the distance formula and the vertices of side PT:
The length of PT is
The same procedure is done for the other 4 sides and the following are the answers:
And by adding all the sides, you get the perimeter:
By rounding off, the answer is 39 units.

(6x - 1) + (5x + 19)=128
Answer:
10
Step-by-step explanation:
add like terms
6x+5x=11x
19-1=18
11x+18=128
subtract 18 from both sides
11x=110
110/11=10
x=10

(This is a question from arithmetic sequence) Jay’s dog weighs 35 kilograms and is overweight. The dog is put on a diet, losing 0.4kg
every week. How long does it take to reach the target weight of 28 kilograms?
Answer:
17.6 weeks
Step-by-step explanation:
The computation of the time taken to reach the target weight is shown below:
35, 34.6, 34.2...............28
As we know that
a_n = a + (n - 1)d
28 = 35 + (n - 1)(-0.4)
28 = 35 -0.4n + 0.4
28 = 35.04 - 0.4n
0.4n = 35.04 - 28
0.4n = 7.04
n = 17.6

Answer:

1.301
Step-by-step explanation
f(x) and g(x) are inverse functions. Note that the logrithmic notation for [tex]f(x) = y = b^{x} \\ is\\ log y_{b} = x[/tex]
So, when x = 1.477, f(x) = y = 30
and when x = 20, g(x) = y = 1.301
Karl starts the engine on his small private airplane. The engine drives a propeller with a radius of 9 feet and its centerline 12.5 feet
above the ground. At idle, the propeller rotates at a constant speed of approximately 750 revolutions per minute. The height of one
propeller tip as a function of time is given by h = 12.5 + 9 sin(7501), where h is the height in feet and t is the time in minutes. Find h
when t= 3.5 minutes.
Answer: The height of one propeller tip is 3.68 feet when t= 3.5 minutes.
Step-by-step explanation:
Given: The height of one propeller tip as a function of time is given by [tex]h = 12.5 + 9 sin(750t)[/tex]), where h is the height in feet and t is the time in minutes.
Put t = 3.5 , we get
[tex]h=12.5 +9 \sin (750\times3.5)\\\\=12.5+9\sin (2625)\\\\=12.5+9(-0.9802)\\\\=12.5-8.8218=3.6782\approx3.68[/tex]
Hence, The height of one propeller tip is 3.68 feet when t= 3.5 minutes.

What is the perimeter of a square if the length of one of the diagonals is 12 cm?
6v2 cm
2412 cm
48 cm
24 cm
Answer:
Step-by-step explanation:
Use Pythagorean theorem to find the length of the square.
Length of the square = a
a² +a² = diagonal²
2a² = 12²
2a² = 144
a² = 144 ÷ 2
a² = 72
[tex]a =\sqrt{72}\\\\ = \sqrt{2*2*2*3*3}\\\\ = 2*3\sqrt{2}\\\\a = 6\sqrt{2}\\\\\\\\Perimeter= 4a\\\\ = 4*6\sqrt{2}\\\\= 24\sqrt{2} cm[/tex]
14) Marketten (100 + x) mL vişne suyu ve (200 + 2x) mL şeftali suyu alan Burak,
toplam 375 mL meyve suyu almış oldu. Buna göre Burak, meyve sularından kaçar mL almıştır?
Burak'ın aldığı vişne suyu miktarı = (100 + x) ml
Burak'ın aldığı şeftali suyu miktarı = (200 + 2x) ml
Burak'ın aldığı toplam meyve suyu miktarı = 375 ml
Bu ifadeler aşağıdaki gibi bir denklem olarak yazılabilir :
[tex] =\tt 100 + x + 200 + 2x = 375[/tex]
[tex] = \tt100 + 200 + x + 2x = 375[/tex]
[tex] =\tt 300 + 3x = 375[/tex]
[tex] = \tt3x = 375 - 300[/tex]
[tex] =\tt 3x = 75[/tex]
[tex] =\tt x = \frac{75}{3} [/tex]
[tex]\hookrightarrow\color{plum}\tt x = 25[/tex]
Böylece x = 25'in değeri
Burak'ın aldığı vişne suyu miktarı :
[tex] =\tt 100 + 25[/tex]
[tex]\color{plum} = \tt125 \: ml[/tex]
Böylece Burak'ın aldığı Berry suyu miktarı = 125 ml
Burak'ın aldığı şeftali suyu miktarı :
[tex] =\tt 200 + 2 \times 25[/tex]
[tex] =\tt 200 + 50[/tex]
[tex]\color{plum} = \tt250 \: ml[/tex]
Böylece Burak'ın aldığı şeftali suyu miktarı = 250 ml
○=> Bu nedenle :
▪︎Burak'ın aldığı meyve suyu miktarı = 125 ml
▪︎Burak'ın aldığı şeftali suyu miktarı = 250 ml
