Q: 20≥-10+w

w≤10

Step-by-step explanation:

Let's solve your inequality step-by-step.

20≥10+w

Step 1: Simplify both sides of the inequality.

20≥w+10

Step 2: Flip the equation.

w+10≤20

Step 3: Subtract 10 from both sides.

w+10−10≤20−10

w≤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
