oksano4ka [1.4K]

Answer:

10 in

Step-by-step explanation:

Let x be the width of the mat width showing around the picture. Since the sheet is 20 in wide by 15 in high, and the perimeter of the mat is 110 in. We have the following equation:

2*(20 + x + 15 + x) = 110

35 + 2x = 55

2x = 20

x = 20/2 = 10 in

I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am pos
Aliun [14]

Answer:

2, 3, 5, 7, 11, 17, 19, 23

Step-by-step explanation:

The segment between  - 15 and 25 has 40 numbers given by

25 - -15

= 25 + 15

= 40

Divided into 4 segments, each would contain 10 numbers  such that the

1st segment is from -15 to -5 (which is -15 + 10)

2nd segment is from -5 to 5 (which is -5 + 10)

3rd segment is from 5 to 15 (which is 5 + 10)

4th segment is from 15 to 25 (which is 15 + 10)

Given that the unknown number is prime and positive this may be

2 or 3 or 5 from the 2nd segment

7 or 11 from the third segment

17 or 19 or 23 from the 4th segment
