Jerry started doing sit-ups every day. the first day he did 13 sit-ups. every day after that he did 2 more sit-ups than he had done the previous day. today jerry did 29 sit-ups. write an equation that could be solved to find the number of days jerry has been doing sit-ups, not counting the first day. let  n  represent the number of days.

an equation that can jerry to find the number of days he has been doing sit-ups is given by

An equation that can help Jerry to find the number of days he has been doing sit-ups is  

Step-by-step explanation:

First day = 13

Second day =  first day + 2 = 13 +2 =15

Third day  =  second day + 2 =  17

Fourth day = Third day +2  = 19

So,

13 , 15 , 17, 19, 21, 23 ...........

The common difference is 2

By using arithmetic series

where

is the number of sit-ups done on the nth day

n is  number of the days

d is the difference

Now

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
