The equation y=1/9x relates proportional quantities x and y.
what is the value of x when y is 4? enter your answer in the box.

x is 36 when y is 4

Step-by-step explanation:

Since the equation is y=1/9x

When y is 4,

enter 4 into the equation

4=1/9x

solve the equation

4×9=x

x=36

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
