1. 1) The solution of x/2 is...2) The solution of 5x = 2x + 3 is...3) The solution of 4x - 5 = 6x - 1 is...4) The smallest member of the solution set of 3x - 7 ≥ 8 is...5) 4x ≤ 5x + 6 equivalent is...
Jawaban:
2.) 5x = 2x + 3
5x-2x = 3
3x = 3
x= 3
jadi solusi x adalah 3
-----------------------------
3.)
4x-5 = 6x - 1
4x - 6x = 5 - 1
-2x = 4
x = 4: -2
x = -2
---------------------------
4.)
3x - 7 ≥ 8
3x ≥ 8 + 7
3x ≥ 15
x ≥ 15:3
x ≥ 3
Anggota himpunan x adalah {1,2,3}. Jadi anggota terkecil adalah 1 (ITU BILA DIKETAHUI BILANGAN X ADALAH BILANGAN ASLI, KALAU BILANGAN YANG LAIN BISA BERBEDA.)
5.)Mencari persamaan atau kesetaraan dari 4x ≤ 5x + 6
4x ≤ 5x + 6
4x - 5x ≤ 6
-x ≤ 6
Jadi persamaannya juga bisa x ≤ -6
Penjelasan:
1). Mohon maaf saya belum bisa jawab karna saya masih bingung sama soalnya. (Mungkin ada yang kurang?)
2.) Jadi itu suruh mencari solusi alias kita mencari nilai x yaitu dengan mengelompokan bilangan dengan pasangannya terlebih dahulu. (Seperti bilangan ber-Variabel dengan ber-Variabel, dan sebaliknya)
3.)Jadi itu suruh mencari solusi alias kita mencari nilai x yaitu dengan mengelompokan bilangan dengan pasangannya terlebih dahulu. (Seperti bilangan ber-Variabel dengan ber-Variabel, dan sebaliknya)
4.) Jadi kita mencari anggota bilangan yang terkecil dari himpunan x yaitu 1. Ingat ya itu klo diketahui himpunan x adalah bilangan x
5.) Jadi itu tuh suruh mencari kesetaraan atau persamaan. yaitu kita ketahui hasilnya -x ≤ 6. Nah itu bisa disamakan dengan x ≤ 6
Sekian terimakasih, mohon maaf ya klo ada yang keliru.
Semoga membantu! =D.

5. What is the pH of 2×10^-5 M sulphuric acid solution
Jawaban
pH = 4
Pembahasan
Asam kuat
sulphuric acid solution = larutan asam sulfat
larutan asam sulfat = H₂SO₄
H₂SO₄ ---> 2H⁺ + SO₄²⁻
a = 2
[H⁺] = a Ma
[H⁺] = 2 x 2. 10⁻⁵
[H⁺] = 10⁻⁴ M
pH = - log [H⁺]

8. One solution of the quadratic equation x^2 + px + 12=0 is 3, then p=... and another solution is...
x² + px + 12 = 0
salah astu penyelesaian x = 3
maka
x² + px + 12 = 0
⇒ (3)² + p(3) + 12 = 0
⇒ 9 + 3p + 12 = 0
⇒ 3p = -21
⇒ p = -7
Sehingga
x² - 7x + 12 = 0
⇒ (x - 3)(x - 4) = 0
maka
x - 3 = 0 ⇒ x = 3
x - 4 = 0 ⇒ x = 4
Jadi, p = -7, dan penyelesaian yang satunya = 4

9. Next, remember that the denominator cannot be 0. This means that x+2≠0→x -2 and x-3 0→x 3. Since x=1/7 satisfies the condition that the denominator is not 0, we can conclude that the value of x is is the solution of (x-1)/(x+2)=(x+1)/(x-3) is x=1/7. 4. The solution to inequality >5 is ....
explanation and steps:
Since the sign of the inequality is , choose a region with a positive or zero sign, namely x≤2/3 or x≥4. The intersection of the results that have been obtained and the conditions are so that the solution to the inequality > 5 is x<-1 or x>17/3.

16. What is the molarity of H2SO4 solution which contains 49.04 g in 1 litre solution.
Materi : Asam - Basa
Answer:
0.500408163236 (0.5 molarity)
Explanation:
to calculate the molarity of sulfuric acid H2SO4.
KNOWN;
m H2SO4 = 49.04 g
v = 1 litre
Mr H2SO4 =
Mr H2SO4
= (2 × Ar h) + (1 × Ar S) + (4 x Ar o)
= (2×1) + (1×32) + (4×16)
= 2+32+6
Mr H2SO4 = 98
(1.The formula for calculating the moles of sulfuric acid
n = m/Mr H2SO4
n = 49.04/98
= 0.50040816326 or 0.5
(2.The formula for calculating the molarity of sulfuric acid
M = n/v
M = 0.50040816336/1
= 0.5
→so the molarity of sulfuric acid H2SO4 is 0.5

17. The solution set of |x + 2| = 10 is? Helpp!
Question:
1. The solution set of |x + 2| = 10 is?
Answer:— For Positive
→ x + 2 = 10
→ x + 2 - 2 = 10 - 2
→ x + 0 = 10 - 2
→ x = 8 ✓
— For Negative
→ x + 2 = -10
→ x + 2 - 2 = -10 - 2
→ x + 0 = -12
→ x = -12

19. What is the solution of 2³×3⁴÷6²
Jawaban:
the solution of your problem
Penyelesaian dari 2³ x 3⁴ : 6² adalah 18.
PembahasanPada bentuk perpangkatan, apabila dalam operasi perkalian dan pembagian terdapat bilangan pokok yang berbeda, maka harus dihitung dahulu masing-masing. Dalam arti, dahulukan perpangkatan, baru selesaikan operasi lainnya.
Dalam hal ini perlu diingat singkatan PaKBaTaK, yaitu pangkat, kali, bagi, tambah, kurang. Artinya perpangkatan didahulukan, diikuti perkalian dan pembagian, selanjutnya penjumlahan dan pengurangan.
Apabila dalam suatu operasi tanpatandakurungmelibatkan perkalian dan pembagian, hitung dari sebelah kiri lalu ke kanan. Begitupun untuk suatu operasi yang melibatkan penjumlahan dan pengurangan.
Lain halnya apabila terdapat tandakurung. Maka operasi di dalam tanda kurung didahulukan.

Penyelesaian:
2³ x 3⁴ : 6² = 8 x 81 : 36
= 648 : 36
= 18
Jadihasildarioperasiperpangkatantersebut adalah18.
