Answer:

3

Step-by-step explanation:

1. Regroup terms.

y+3=9−y

2. Subtract 33 from both sides.

y=9-y-3y=9−y−3

3. Simplify  9-y-39−y−3  to  6-y6−y.

y=6-yy=6−y

4. Add yy to both sides.

y+y=6y+y=6

5. Simplify  y+yy+y  to  2y2y.

2y=62y=6

6. Divide both sides by 22.

y = 6/2

7. Divide

y = 3

jolli1 [7]

Answer:

\frac{3}{20}

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is \frac{3}{8} text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text =\frac{3}{8}x

Remaining part =x-\frac{3}{8} x

Remaining part =\frac{8x-3x}{8}=\frac{5}{8} x

Therefore, a newspaper;s cover page fill with  Photograph =\frac{5}{8}

If the article about endangered species=\frac{2}{5} of text

Therefore, the article about endangered species=\frac{2}{5}\times\frac{3x}{8}=\frac{3}{20}x

Hence,  the article about endangered species is \frac{3}{20}of the cover page.
