R=12 because in order to get rid of the 2 in the denominator you have to multiply both sides by 2. Then the equation reads 9r-18<90. Next add the 18 to her 9r<108. And lastly divide by 9 to solve for r. Which in this case is 12

diamong [38]

Answer:

9 pieces

Step-by-step explanation:

28 inches rope cut into 3-inch pieces

28/3 = 9 1/3

There is no matching answer choice, if given numbers are correct then the answer is 9 full pieces

---------

The close answer choice is 8
28/8 = 3 1/2 or 3.5
So if cut into 3.5 inch pieces then it is 8 full pieces
just in case it was typo 3 instead of 3.5
