30 = 12d
d = 30/12 = 15/6 = 5/2 = 2 1/2
check 12*2 + 6 = 24+6 = 30 sure enough
The answer to 30=12d
d=18
30=12d, this means 30 is equal to 12*?
You have to find the missing variable, so d would equal 2.5, or 2 1/2
30=12d
Divide both sides by the co-efficient.
12/12 leaves you with d.
30/12 leaves you with 2.5
D=2.5
Check your work.
30= 12*2.5
12*2.5= 30
30=30
simplify 6 12/18
To find the value of "d" in the equation 30 = 12d, we need to isolate "d" on one side of the equation.
Here's how the equation can be solved step-by-step:
1. Start with the equation: 30 = 12d.
2. To isolate the variable "d," divide both sides of the equation by 12:
30 ÷ 12 = (12d) ÷ 12.
Simplifying the left side gives:
2.5 = d.
Therefore, the value of "d" in the equation 30 = 12d is 2.5.
