Sixty more than nine times a number is the same as two less than ten times the number. What is the number?
1. Sixty more than nine times a number is the same as two less than ten times the number. What is the number?
Sixty more than nine times a number --> 9a + 60
two less than ten times the number --> 10a - 2
9a + 60 = 10a - 2
60 + 2 = 10a - 9a
62 = a
a = 62
2. I think of a number, the number is an even number. If I add 12 to it, the new number will be equal to 4 times of number 9. The number that I thought is bantu jawab ya makasih

Jawab:
Prime number less than 12
Jawaban:
{ prime number less than 12}.
Penjelasan dengan langkah-langkah:
himpunan dalam ilmu matematika adalah kumpulan objek yang memiliki sifat yang dapat didefinisikan dengan jelas
5. Known, A = {2, 3, 5, 7, 11}. The possible universal set of set A is. . . . A. { natural number less than 12}. B. { odd number less than 12 }. C. { whole number between 2 and 11}D. { prime number less than 12}.
Jawaban:

6. For items 4 to 5, refer to the given problem below:If 12 is subtracted from 3 times the square of a positive number the result is 5 times the number. What is the original number?4. Which of the following equations would best represent the problem?A. 3x2 - 12 = -5xC. 3x2 - 12 = 5xB. 12 - 3x2 = -5xD. 12 - 3x2 = 5x5. What is the original number?A 3C. 5B. 4D. 6
Answer:
4. C. 3x² - 12 = 5x
5. A. 3
Solution:
4.
Let the original number be x.
12 subtracted from ( 3 times the square of a positive number ) would be 3x² - 12
5 times the number is 5x
Therefore the answer for number 4 is C, 3x² - 12 = 5x
5.
The option 5 can be excluded as 12 is not a multiple of 5.
if x is 3:
3 × 9 - 12 = 5 × 3
15 = 15, which is true
If x is 4:
3 × 16 - 12 = 5 × 4
36 = 20, which isn't true.
if x is 6:
3 × 36 - 12 = 5 × 6
96 = 30, which also isn't true.
So the answer for number 5 is A, 3

9. The sum of two numbers is 49.6. One of the number is 9 times the other number. ,What is the two number?
Jawab:
Penjelasan dengan langkah-langkah:
Kita beri permisalan angka pertama = a dan agka kedua = b
a+b=49,6
ax9=b
kita subtitusikan ax9=b ke dalam a+b=49,6
a+b=19,6
a+(ax9)=49,6
10a=49,6
a=4,96
b=ax9
=4,96x9
=44,64
10. the sum of three times a number and 11 is 32 .write the expression
Jawaban:

11. 1. I think of a number and subtract 33. the answer is 5. what is the number? 2. A number times 11 is 132. what is the number? 3. A number divided by 13 is 4. what is the number? 4. I think of a number and add 8. the answer is 32. what is the number? TOLONG BANTU KAK SEKALIAN KLO ADA CARANYA
1.
x - 33 = 5
x = 5 + 33
x = 38
2.
x . 11 = 132
x = 132 : 11
x = 12
3.
x : 13 = 4
x = 4 . 13
x = 52
4.
x + 8 = 32
x = 32 - 8
x = 24
12. Five is subtracted from 4 times a number and the result is then doubled. If the answer is 6, what is the original number?
Jawaban:
2
Penjelasan:
2 x (4A - 5) = 6
4A - 5 = 6/2 = 3
4A = 3 + 5 = 8
A = 8/4 = 2
13. ABCDE is a five digit number, ABCDE1 is three times 1ABCDE. What is ABCDE?
menggunakan aljabar
[tex]ABCDE[/tex] bisa ditulis menjadi
[tex]10000A + 1000B + 100C + 10D + E = 10^4A + 10^3B + 10^2C + 10^1D + 10^0E[/tex]
bisa kita misalkan
[tex]x = 10^4A + 10^3B + 10^2C + 10^1D + 10^0E[/tex]
dari yang ada di pertanyaan
[tex]ABCDE1[/tex] bisa ditulis menjadi
[tex]ABCDE1 = 10^5A + 10^4B + 10^3C + 10^2D + 10^1E + 1\\
= 10(10^4A + 10^3B + 10^2C + 10^1D + 10^0E) + 1\\
= 10x + 1[/tex]
dan yang satunya [tex]1ABCDE[/tex] bisa ditulis menjadi
[tex]1ABCDE = 10^5 + 10^4A + 10^3B + 10^2C + 10^1D + 10^0E\\
= 10^5 + x[/tex]
sehingga, pernyataan di soal dapat ditulis menjadi
[tex]10x + 1[/tex] adalah tiga kalinya [tex]10^5 + x[/tex]
maka
[tex]10x+1 = 3(10^5 + x)\\
10x + 1 = 3\times10^5 + 3x\\
7x = 3\times10^5 - 1\\
7x = 299999[/tex]
maka
[tex]\boxed{x=42857}[/tex]
14. three times a number is the same as 2½ of a number increased by 6. Find the number! pake pengertian dan cara nya ya!!!
tiga kali sebuah angka sama dengan 2,5 dari sebuah angka ditambah 6. Temukan angkanya!
3x = 2,5x + 6
3x - 2,5x = 6
0,5x = 6
x = 0,5 : 6
x = 12
