In AABC, point D is on AB, and point E is on BC

Serhud [2]

Answer:

$AC=\frac{27}{2}$

Step-by-step explanation:

We are given a Triangle ABC , and DE││BC , where D and E lies on AB and BC Respectively. As DE││BC , ABC is similar to BDE. Hence the ratios of the respective sides will be equal . Hence

$\frac{BD}{AB}=\frac{DE}{AC}$ ----------(A)

Given BD=2

BA=BD+AD=2+7=9

DE=3

Putting these values in (A)

$\frac{2}{9}=\frac{3}{AC}$

$AC= \frac{3 \times 9}{2}$

$AC=\frac{27}{2}$

Sally is making bouquets of flowers with the ratio of red to white flowers being 2:3. If Sally used 12 red flowers, how many whi

alexandr402 [8]

Answer:

18 white flowers

Step-by-step explanation:

We are given ratio:

Red : White

2 : 3

If Sally used 12 red flowers, how many white flowers will she use?

Let the number of white flowers Sally uses be represented by x

This is calculated as:

2/3 = 12/x

Cross Multiply

2 × x = 3 × 12

x = 3 × 12/2

x = 18 white flowers

Therefore, if Sally used 12 red flowers, the number of white flowers will she use is 18 white flowers.
