[9(x - 9) = -11\ 9x-81=-11\ 9x=70\ x=\frac{70}{9}
]
To solve the equation 9(x − 9) = − 11, we first need to distribute the 9 on the left side of the equation:
9x - 81 = -11
Next, we add 81 to both sides of the equation to isolate the term with the variable x:
9x = 70
Finally, we divide both sides by 9 to solve for x:
x = 70 / 9
The final answer is x = 70/9, which corresponds to option E.
The solution to the equation 9 ( x − 9 ) = − 11 is found by distributing, isolating x , and simplifying, leading to x = 9 70 . Thus, option E is the correct choice.

Jawaban:Rp 15.000,0 IDR artinya lima belas ribu rupiah. Jadi:---✅ Jawaban:> Rp 15.000,0 IDR = Rp 15.000 (lima belas ribu rupiah)Penjelasan: Penjelasan:IDR adalah singkatan dari Indonesian Rupiah, yaitu mata uang resmi Indonesia.Angka 15000.0 hanya menunjukkan angka desimal biasa (ada koma nol), tapi nilainya tetap sama dengan Rp 15.000.Jadi tidak ada perubahan nilai—itu tetap lima belas ribu rupiah, hanya beda dalam penulisan angka.
