Solve -9 2/7 - (-10 3/7)

1 1/7

Step-by-step explanation:

positive 10 3/7- 9 2/7 is equal to 1 1/7

Subtracting a negative number is the same as adding a positive number.

-9 2/7 - (-10 3/7)

-9 2/7 + 10 3/7

Turn both into improper fractions.

-9 2/7 = -65/7

10 3/7 = 73/7

Add.

-65/7 + 73/7

8/7 or 1 1/7

Best of Luck!

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
