“Now solve the proportion for the missing number”

13/2 = ?/12

78

Step-by-step explanation:

2*6=12

13*6=78

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

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
