Express each ratio as a fraction in simplest form.
5 miles to 35 miles

1 : 7

Step-by-step explanation:

Given

5 miles : 35 miles ( divide both parts by 5 )

= 1 : 7 ← in simplest form

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
