kotegsom [21]
I believe the correct answer is 15, because 15/8 x 15/1= 225/8 and when you simplify that you get 28 with 1/8 left over.

Answer:

1.35kg

The length of the top of a computer desk is 2 1/4 feet longer than it’s width. If it’s width measures y feet, express its length
Lera25 [3.4K]

Answer:

The length as an algebraic expression in y is  y   + (2\frac{1}{4} )  ft

Step-by-step explanation:

The measure of the width of the computer desk = y feet

The measure of the length of the desk = width + 2  1/4 ft

⇒Measure of Length = y   + (2\frac{1}{4} )   ft

Hence, the length as an algebraic expression in y is  y   + (2\frac{1}{4} )   ft
