The length of a rectangle is 5 more than 3 times the width. Write and solve ad equation to find the width(w) if the length is 12.5cm
12.5= 5 + 3w
w=2.5cm
is this correct? thank you.
Yes, it's correct.
Yes, your solution is correct!
To solve this problem, you correctly set up an equation based on the given information: "The length of a rectangle is 5 more than 3 times the width."
Let's break down the equation:
Length = 5 + (3 * Width)
You're given that the length is 12.5 cm, so you substitute it into the equation:
12.5 = 5 + (3 * Width)
Next, you simplify the equation:
12.5 - 5 = 3 * Width
7.5 = 3 * Width
To isolate the width, you divide both sides of the equation by 3:
7.5 / 3 = Width
Finally, you solve for the width:
Width = 2.5 cm
Therefore, the width of the rectangle is 2.5 cm.
12.5= 5 + 3w
w=2.5cm
is this correct? thank you.
