At the donut shop the cost for a dozen donut holes and a glass of milk is $3.65. the cost for 3 dozen donut holes and 5 glasses of milk is $13.65. which pair of equations can be used to determine d, the cost of a dozen donuts holes, and m, the cost of a glass of milk? a. d + m = 3.65 5d + 3m = 13.65 b. d + m = 13.65 5d + 5m = 3.65 c. d + m = 3.65 3d + 5m = 13.65 d. d + m = 3.65 3d + 3m = 13.65 '

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.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
