33/4 x = 1 1/4
7/5 x = 7/15

x has to be the same in both equations.

x = 1/3

Step-by-step explanation:

3 3/4x = 1 1/4

15/4x = 5/4

x = 5/4 * 4/15

x = 5/15 which reduces to 1/3

7/5x = 7/15

x = 7/15 * 5/7

x = 7/21 which reduces to 1/3

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
