Solve for the missing variable, PLEASE HELP! I know its a lot- I Will give brainiest for ALL correct answers!!! Solve for missing variable:
-3x +9= -18
2x -14 = -9
x/2 +8 = -24
-2.5x -10 = 40
-6x -10 = 20
50= 2x + 12
x/2 - 7 = -10

THANK YOU ALL! <3 (´▽`ʃ♡ƪ)

1. x = 9

2. x = 5/2

3. x = -64

4. x = -20

5. x = -5

6. x = 19

7. x = -6

Step-by-step explanation:

1.

-3x + 9 = -18

-3x = -27

x = 9

2.

2x - 14 = -9

2x = 5

x = 5/2

3.

x/2 + 8 = -24

x/2 = -32

x = -64

4.

-2.5x - 10 = 40

-2.5x = 50

x = -20

5.

-6x - 10 = 20

-6x = 30

x = -5

6.

50 = 2x + 12

38 = 2x

19 = x

x = 19

7.

x/2 - 7 = -10

x/2 = -3

x = -6

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

sine
