Answer:The value of d that solves the equation D/4 - (-5) = 9 is d = 16.

Step-by-step explanation:To solve for d in the equation D/4 - (-5) = 9, we can follow these steps: 1. Simplify the equation by performing the operation inside the parentheses. The negative sign in front of the 5 indicates subtraction, so -(-5) becomes +5. The equation becomes D/4 + 5 = 9. 2. Next, we can isolate the variable d by subtracting 5 from both sides of the equation to get D/4 = 9 - 5. This simplifies to D/4 = 4. 3. To eliminate the fraction, we can multiply both sides of the equation by 4. This gives us (4)(D/4) = (4)(4), which simplifies to D = 16.

Answer:

d = 16

Step-by-step:

⇒ d/4-(-5) = 9

  • -(-x) = x

⇒ d/4 + 5 = 9

⇒ d/4 = 9 -5

⇒ d/4 = 4

⇒ d = 4(4)

⇒ d = 16
