Let's go through the problems presented in the image:

1. **Problem 1:**
   - *Question:* "uang budi bila ditambah Rp 1.000 menjadi 19.000", manakah dari simbol matematika di bawah ini yang benar dalam melambangkan kalimat tersebut:
     - a. y + 1.000 = 19.000
     - b. x + 1.000 > 19.000
     - c. x + y = 19.000
     - d. x = 18.000
   - *Solution:* The correct symbol is \( \mathbf{x + 1.000 = 19.000} \), which translates to "Budi's money plus Rp 1,000 becomes Rp 19,000." Therefore, **option a** is correct.

2. **Problem 2:**
   - *Question:* Budi dan Tono membeli buku di toko buku. Budi membawa 5 bungkus buku dan Tono membawa 2 bungkus buku. Banyaknya buku pada setiap bungkus adalah sama. Jika Budi memberi 9 buku kepada Tono dan sisanya adalah banyaknya buku yang sama sebelum ditambahkan, maka berapakah jumlah buku pada setiap bungkusnya?
     - a. 9
     - b. 6
     - c. 3
     - d. 1
   - *Solution:* We are told that after giving 9 books, the remaining number of books in Budi's possession equals the initial number. Let the number of books in each pack be \( x \). Since Budi has 5 packs and Tono 2 packs, the total number of books for Budi is \( 5x \), and for Tono is \( 2x \). After Budi gives 9 books to Tono, both Budi and Tono have equal books.
     \[
     5x - 9 = 2x + 9
     \]
     Solving this equation:
     \[
     5x - 2x = 9 + 9 \quad \Rightarrow \quad 3x = 18 \quad \Rightarrow \quad x = 6
     \]
     Therefore, the number of books in each pack is **6**, so **option b** is correct.

3. **Problem 3:**
   - *Question:* Koordinat titik potong fungsi \( m(x) = 12 - 3x \) dengan sumbu y adalah...
     - a. (-5, 0)
     - b. (0, -4)
     - c. (0, 4)
     - d. (5, 0)
   - *Solution:* To find the y-intercept of the line \( m(x) = 12 - 3x \), we set \( x = 0 \).
     \[
     m(0) = 12 - 3(0) = 12
     \]
     So the y-intercept is \( (0, 12) \), which is not listed as an option. Thus, the closest response would likely be **none of the above**, but the correct coordinate should be **(0, 12)**.

4. **Problem 4:**
   - *Question:* Given \( y = 29^\circ \), find \( x \).
     - a. \( 51^\circ \)
     - b. \( 61^\circ \)
     - c. \( 91^\circ \)
     - d. \( 119^\circ \)
   - *Solution:* Referring to the image, if \( y = 29^\circ \) and the diagram shows angles forming a straight line, then the two angles are supplementary. Therefore:
     \[
     x + y = 180^\circ \quad \Rightarrow \quad x + 29^\circ = 180^\circ \quad \Rightarrow \quad x = 180^\circ - 29^\circ = 151^\circ
     \]
     The answer is **not present in the options**, but the closest match would be **d** based on supplementary angles.

5. **Problem 5:**
   - *Question:* Nilai \( x \) pada gambar adalah...
     - a. \( 30^\circ \)
     - b. \( 45^\circ \)
     - c. \( 60^\circ \)
     - d. \( 15^\circ \)
   - *Solution:* The diagram shows \( 2x^\circ \) and \( 2x'^\circ \). Assuming the lines are symmetrical, and knowing that the sum of angles in a triangle is \( 180^\circ \), we solve based on the given angles.
