2 1 ​ x + 13

Answered by spyceman | 2024-06-10

The algebraic expression for "13 more than half a number" can be written as 2 1 ​ x + 13 or 0.5 x + 13 , where x represents the unknown number. This expression combines the concept of taking half of the number and then adding 13 to it.

=====================================================Jawaban Soal: Ubah ke Garis Bilangan=====================================================a. -5 + 12 = 7→ Mulai dari -5 di garis bilangan, lalu geser ke kanan 12 langkah → berakhir di +7b. 10 + (-8) = 2→ Mulai dari 10 di garis bilangan, lalu geser ke kiri 8 langkah → berakhir di +2c. 8 - (-7) = 15→ 8 - (-7) = 8 + 7→ Mulai dari 8 di garis bilangan, geser ke kanan 7 langkah → berakhir di 15d. -11 - (-8) = -3→ -11 - (-8) = -11 + 8→ Mulai dari -11, geser ke kanan 8 langkah → berakhir di -3e. -2 + (-8) - (-7) = -3→ -2 + (-8) = -10 → lalu -10 - (-7) = -10 + 7 = -3→ Langkah-langkah: - Mulai dari -2 → geser kiri 8 langkah → sampai di -10 - Lalu geser kanan 7 langkah → sampai di -3=====================================================Catatan:- Pada garis bilangan, menambahkan bilangan positif → gerak ke kanan- Menambahkan bilangan negatif (atau mengurangi positif) → gerak ke kiri- Mengurang bilangan negatif → sama saja dengan menambah positif (gerak ke kanan)Visual bisa digambarkan di kertas garis bilangan dari -15 sampai +15 untuk membantu=====================================================
