An electrician charges $40 to come to your house. She also chargers $50 for each hour that she works. The electrician charges a total of $190. How many hours did the electrician work at your house? A.40x + 50 > 190
B.40 + 50x < 190
C.50x + 40 = 190
D.50x - 40 = 190

C if im right because 40 - 190 is 150 and she worked 3 hours 50 50 50 = 150

3 hours

Step-by-step explanation:

1. $40 - $190 = $150, the electrician charged $40.

2. $150 divided by $50 = 3, since the electrician charges $50 per hour, they stayed for 3 hours.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

answer: 0.1,0.85
