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.

A pet survey found that the ratio of dogs to cats is 2/5. Write and solve a proportion that shows the number of dogs

Irina18 [472]

So,

The ratio of dogs to cats:
$\frac{2}{5}$

The other proportion:
$\frac{x}{140}$

$\frac{2}{5} = \frac{x}{140}$

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1
$\frac{2}{5} * \frac{28}{28} = \frac{56}{140}$

There are 56 dogs when the number of cats is 140.

Natalija [7]

Make her feel important and good about herself. Compliment her, never put her down, and always encourage her to reach for the things she wants. Let her know when you see her do something well, even if it's just something small like helping someone else.
