1. 4) Which of the following represents all the possible values of x that satisfy the equation below? X X x − 3 2x 2 *
Nilai x memenuhi persamaan yaitu x = 0 atau x = 4. Soal ini berkaitan dengan materi mencari nilai x dari suatu persamaan.
Penjelasan dengan langkah-langkahDiketahui :
Koreksi soal, mungkin maksud Anda persamaan x/(x-3) = 2x/2
Ditanyakan :
Solusi dari permasalahan tersebut
Jawab :
Langkah 1
x / (x - 3) = 2x / 2
Jika dipindah ruas akan menjadi :
x . 2 = 2x . (x – 3)
Selanjutnya kita lakukan operasi
2x = [tex]2x^{2}[/tex] – 6x
0 = [tex]2x^{2}[/tex] – 8x
0 = 2x (x – 4)
x = 0 atau x = 4
Jadi, x yang memenuhi adalah x = 0 atau x = 4

equation represents the standard enthalpy change of formation of water
is 2H2(g)+O2(g)→2H2O(l)
4. An equation is given below. 4(x - 7) = 0.3(x + 2) + 2.11 The solution to the equation is A. 8.3 B. 8.7 C. 3 D. -3
Jawaban:
4.53
Penjelasan dengan langkah-langkah:
4x - 14 = 0.3x + 0.6 + 2.11
3.7 x = 16.76
x = 4.53
5. create an equation from the word below•best•big• cool•amazing
1) my best friend is beni
2) the house is very big
3) the guy is so cool
4) You do flips that's amazing
6. solve the equation below x^2 = 3x + 2 = 0
Assume that the typo in the right side of x² is a pus (+) symbol.
So,
x² + 3x + 2 = 0
Factorize it.
(x+1)(x+2) = 0
Get some radixes:
x₁ + 1 = 0
x₁ = -1
x₂ + 2 = 0
x₂ = -2
So, the solution of the equations are:
x = {-2,-1}
[tex]\displaystyle x^2+3x+2=0\\x^2+2x+x+2=0\\x(x+2)+1(x+2)=0\\(x+1)(x+2)=0\\\\x+1=0\\x=-1\\\\\text{or}\\\\x+2=0\\x=-2\\\\\boxed{\boxed{S=\{-1,-2\}}}[/tex]
7. 3) 0.1 mol of lithium reacts with excess oxygen gas. (a) Write a balanced chemical equation for the reaction. (b) Calculate the mass of the product formed.
Jawaban:
Penjelasan:
(a) A balanced chemical equation for the reaction is:
2Li + O2 -> 2Li2O
(b) To calculate the mass of the product formed, we can use the molecular weight of lithium oxide (Li2O). The molecular weight of Li2O is 30.8 g/mol. Therefore, the mass of 0.1 mol Li2O is 3.08 grams.
8. solve the equation below 3 - 2x - x^2 = 0
Use some tricks.
[tex]$\begin{align}3-2x-x^2&=0 \\ \text{Multipty both }& \text{sides by (-1)} \\ (-1)(3-2x-x^2)&=(-1)(0) \\ -3+2x+x^2&=0 \\ x^2+2x-3&=0 \\ (x+3)(x-1)&=0\end{align}[/tex]
The correct x are:
x = {-3,1}
[tex]x^2-x+3x-3=0 \\ \\ x(\frac{x^2}{x}-{x}{x}+3(\frac{3x}{3}-\frac{3}{3})=0 \\ \\ x(x^{2-1}-1)+3(x-1)=0 \\ \\ (x-1)(x+3)=0 \\ \\ \\ x-1=0 \\ \\ x+3=0 \\ \\ x=1 \ dan \ x=3 \\ \\[/tex]
Jadi x∈{1,-3}
