Try this: Add up the given widths of the first 3 bookcases, in cm. This will be a constant. Now write "-2w" after that sum, to represent two more bookcases of unknown widths w. Finally, use the inequality symbol (less than or equal to) and the given wall length to complete this inequality.

Solve it for w, writing your answer as another inequality.

Sally has 2 cats and each cat eats 1/4 of a tin of cat food each day.

Mashutka [201]

If one cat eats 1/4 of a tin per day then two cats eat 1/2 of a tin per day.

We have 9 tins so if each day cats eat 1/2 we have to divide 9 with 1/2 and we get 18 which is for how many days she can feed the cats until she runs out of food.

Hope this helps.
