Need to write an equation for kims age is 4 times of her sister when you add kims age to her sisters age you get 60. how old is each sister

Let kims sister age be x

Kims age=4 times x= 4x

Kims age+Kims sister age=60

Hence,4x+x=60

4x+x=5x

5x=60

x=60/5

=12

Kims age=4x

=4*12=48

kims sisters age=x

=12

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
