Circles = 5

Answer 2

Number of circles in a photo album =5

Number of rectangles in a photo album =60

Number of squares in a photo album =15

Explanation:

We are given that in a photo album

There are total number of pictures=80

Each picture is in the shape of a square , a rectangle or a circle.

We have to find the number of each type of picture in the photo album.

Let number of circles in photo album=x

Number of rectangles a photo album=12x

Number of square in a photo album=x+10

Total picture in a photo album=80

Substitute the values then we gte

`x+12x+x+10=80`

`14x=80-10`

`14x=70`

`x=(70)/(14)`

`x=5`

Number of circles =5

Number of rectangles=
`12* 5=60`

Number of squares=x+10=5+10=15
