Terry’s age is 3 less than three times Cody’s age. The sum of their ages is 57. How old are Terry and Cody?

let Cedric's age be c

tyshon= 3c-3

3c-3 +c =3c+c-3 = 4c-3

4c-3=57

4c=60

c=15

tyshon=15×3-3 = 42

16

Step-by-step explanation:

57dvied by 3 -3=16

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

18.75 gallons
