1. 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
HP = {-12 , 8}2. 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 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
hope it helps, thank you
6. A solution is made by dissolving 25 g of glucose, C₆H₁₂O₆, to make 500 cm³ solution. What is the concentration of the solution in g/dm
Jawaban:
Calculating concentrations
The concentration of a solution can be shown in g/dm3 or mol/dm3. It is often more useful to know the concentration of a reactant in mol/dm3 so that the amount of reactant in a given volume can be calculated.
7. 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.

13. If 0 < a < 1, so the solution set of inequality a is...
If 0 < a < 1, the solution set of inequality a is all real numbers that are greater than 0 and less than 1.
In other words, the solution set of the inequality a is the interval (0,1), which includes all real numbers x such that 0 < x < 1.
For example, if a = 0.5, then the solution set of the inequality a is the interval (0,1), which includes all real numbers x such that 0 < x < 1. This interval includes all numbers between 0 and 1, including 0.5.
If a is any other number between 0 and 1, the solution set of the inequality a will also be the interval (0,1).
I hope this helps!
