The work of a student to solve the equation 3(3x -4) = 8 + 2x +5 is shown below: step 1: 3(3x -4) = 8 + 2x +5 step 2: 6x - 7 = 13 +2x step 3: 6x -2x = 13 + 7 step 4: 4x = 20 step 5: x = 5 in which step did the student first make an error and what is the correct step?

Step 2

Step-by-step explanation:

7

step-by-step explanation:

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
