Solve: 3x - 2x + 4 = 5x - 4x - 8
A) 3
B) 6
C) -3
D) no solution

There are no values of x that make the equation true.

D) No solution

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

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
