Two numbers are such that is 9 is added to the first number, so the number become three times the second number. And ,if 22 is added to the second number So the number obtained is twice the first number. Find the differences both of number!
1. Two numbers are such that is 9 is added to the first number, so the number become three times the second number. And ,if 22 is added to the second number So the number obtained is twice the first number. Find the differences both of number!
[tex]a =the \: first \: number \\ b =the \: second \: number \\ \\ 9 + a = 3b \\ a = 3b - 9 \\ \\ 22 + b = 2a \\ 22 + b = 2(3b - 9) \\ 22 + b = 6b - 18 \\ 22 + 18 = 6b - b \\ 40 = 5b \\ \frac{40}{5} = b \\ b = 8 \\ \\ a = 3b - 9 = 3(8) - 9 \\ a = 24 - 9 = 15[/tex]
The difference both of number

5. if the average of three numbers is V. If one of the number is Z and another is Y, what is the remaining number?
V = (y + z + remain.nmbr) / 3
3v = y + z + remaining number
Remaining number = 3v - y - zLet consider that the remaining number is: X, then
X + Y + Z
------------- = V ===> multiply both sides by 3
3
X + Y + Z = 3V ===> X = 3V - Y - Z
so, the remaining number is: 3V - Y - Z
hopefully my answer is clearly enough
6. The sum of three number is 109The second number is 4 times the first and the third is 8 less than the second . Find the three number.
Jawaban :
Pembahasan :
a + b + c = 109
b = 4a
c = b - 8
a + b + c = 109
a + 4a + b - 8 = 109
a + 4a + 4a - 8 = 109
9a - 8 = 109
9a = 109 + 8
9a = 117
a = 13
b = 4a
b = 4(13)
b = 52
c = b - 8
c = 52 - 8
c = 44

12. The difference between two numbers is three. If the square of the smaller number is equal to four times the larger number, find the two numbers
Penjelasan dengan langkah-langkah:
Suppose
x = smaller number
y = larger number
Difference between two numbers is three
x - y = 3
x = y + 3
Square of the smaller number is equal to four times the larger number
x² = 4y
4y = x²
4y = y² + 6y + 9
y² + 6y + 9 = 4y
y² + 2y + 9 = 0
Using the abc's formula, we know that y isn't real numbers. So we can't find the value of x and y.
13. Another numberBefore you read find the meaning of these wordsOnce = Sekali Four times = ______________Twice = ___________ Twenty times = ______________Three times = Tiga kali One hundred times = Seratus kaliAnd so next……….
four time : empat kali
twice : dua kali
twenty times : dua belas kali
Twice : dua kali
Four times : empat kali
Twenty times : dua puluh kali
Times digunakan sebagai kata "kali" yang menunjukkan pengulangan terhadap suatu peristiwa/kegiatan. Contoh : Ran the schoolyard twice. (Lari halaman sekolah dua kali) menunjukkan pengulangan lari selama dua kali.

16. 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
17. 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]
18. when 32 us added to 70% of a number, the number is the answer. Find the number.
Jawab:
When 32 us added to 70% of a number, the number is the answer. Find the number!
32 + 70%x = x
100%x - 70%x = 32
30x/100 = 32
x = 3200/30
x = 106, 67
I hope this helps!
