#20 four times the sum of number. and 15 is a least20. Let X represent the number. :find ball possible values for X
gayaneshka [121]
For this case what we have to take into account is the following variable:
 x = represent the unknown number
 We now write the following inequality:
 "four times the sum of number and 15 is at least 20"
 4 (x + 15)> = 20
 We clear the value of x:
 (x + 15)> = 20/4
 (x + 15)> = 5
 x> = 5 - 15
 x> = - 10
 The solution set is:
 [-10, inf)
 Answer:
 
all possible values for X are:
 
[-10, inf)

An arithmetic sequence is represented in the following table. Enter the missing term of the sequence.
Allisa [31]

Answer:

329.5

Step-by-step explanation:

From the table we see that the common difference d = 0.5 - (-6.5)

= 7, and 7.5 - 0.5 = 7. Also 14.5 - 7.5 = 7.

The first term a1 = -6.5.

The nth term = a1 + (n - 1)d  so for our sequence we have:

49th term =  -6.5  + (49 - 1)7

= -6.5 + 48 * 7

= -6.5 + 336

= 329.5   (answer).
