Enter the number that belongs in the green box.

x = 10

Step-by-step explanation:

If you look at the opposite side of the "x", you see the same shape, with the same values.

You can see a congruent shape on the left side of the figure.

x = 10

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

a is the right answer
