a = lilies

13 - a = tulips

We have: 1.25a + 0.90(13 - a) = 14.85

=> 1.25a + 11.7 -0.90a = 14.85

=> 0.35a = 14.85 - 11.7 = 3.15

=> a = 3.15 ÷ 0.35 = 9

=> She bought 9 lilies and 4 tulips

Negative two and one-fourth divded by negative one and one-half

Bond [772]

Answer:

The answer is 3/2 or 1 1/2

Step-by-step explanation:

First, you have to make it as a improper fraction :

$- 2 \frac{1}{4}$

$= - \frac{( 2 \times 4) + 1}{4}$

$= - \frac{9}{4}$

$- 1 \frac{1}{2}$

$= - \frac{(1 \times 2) + 1}{2}$

$= - \frac{3}{2}$

Next, you can divide it by cutting out the common factor :

$- \frac{9}{4} \div - \frac{3}{2}$

$= - \frac{9}{4} \times - \frac{2}{3}$

$= - \frac{ 3}{2} \times - 1$

$= \frac{3}{2}$

$= 1 \frac{1}{2}$
