Answer:
Step-by-step explanation:
5(d - 68) = 85
Use distributive property
5*d - 68*5 = 85
5d - 340 = 85
Add 340to both sides
5d = 85 + 340
5d = 425
Divide both side by 5
d = 425/5
d = 85
Answer:
The width of rectangle is 1 unit.
Step-by-step explanation:
Given:
The area of rectangle is 6 units and its width is 5 units less than the length.
So, to find the width of rectangle.
Let the length be
and the width be
.
Now, to find the width we put the formula of area of rectangle:
Area = length × width






<em>On solving equation we get:</em>

Therefore, we take the value x=6 as it is positive value:


So, the width of rectangle:
Width = 
= 
= 
Therefore, the width of rectangle is 1 unit.
