The problem to solve is:
d/5>4
First, let's work on the left hand side of your inequality, the d/5
This means, for instance, to see if it can be simplified at all.
To divide d by 1 The d just gets copied along in the numerator.
The answer is d
d/5 evaluates to 1/5d
So, all-in-all, the left hand side of your inequality can be written as:1/5d
Now, let's work on the right hand side of your inequality, the 4
The right hand side of your inequality can be written as: 4
So with these (any) simplifications, the inequality we'll set out to solve is:
1/5d > 4
To isolate the d, we have to divide both sides of the inequality by the other "stuff" (variables or coefficients)
around the d on the left side of the inequality.
The last step is to divide both sides of the inequality by 1/5 like this:
To divide d by 1
The d just gets copied along in the numerator.
The answer is d
1/5d ÷ 1/5 = d
4 ÷ 1/5 = 20
The solution to your inequality is:
d > 20
So, your solution is:
d must be greater than 20.
HOPE THIS HELPS!
