Jamal uses the steps below to solve the equation 6x – 4 = 8. step 1: 6x – 4 + 4 = 8 + 4 step 2: 6x + 0 = 12 step 3: 6x = 12 step 4: = step 5: 1x = 2 step 6: x = 2 which property justifies step 3 of his work? a). the addition property of equality b). the identity property of addition c). the multiplication property of equality d). the identity property of multiplication

B). the identity property of addition

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
