Answer:
5. 8n
6. 8 + 3n
7. 18 - 3D
8. [tex]\frac{1}{4}(15+x)[/tex]
9. 15 + 2D
Step-by-step explanation:
5. Let's assign a number as 'n'. In this question, it is asking for the product of twice a number and four. We can write this as: 2n · 4, or 8n.
6. 8 Increased by three times a number can be written as:
8+ 3n
7. If we are subtracting "3 times D", we can write it as: 18- 3D.
8. One-forth of '15+x' becomes [tex]\frac{1}{4}(15+x)[/tex].
9. Adding the product of "2 and D" to 15 gives us 15 + 2D.
