6. Choose the step to take to solve this equation for x. -7 + x = 8

a) subtract 7 from the left
b) subtract 7 from both sides
c) add 7 to the right
d) add 7 to both sides

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
