And the last question is: the sum of two consecutive integers is at least 14. what is the least possible pair of integers? a) 4 and 5 b) g and 7 c) 7 and 8 d) 8 and 9

7 and 8

Step-by-step explanation:

Given The sum of two consecutive integers is at least 14.

Let the two consecutive digits be x and x+1

The condition that should be satisfied by these numbers is that their sum must be atleast 14.

Since x is an integer x=7 and the other digit is 8.

c is the answer

step-by-step explanation:

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
