Answer:
x = 20
Step-by-step explanation:
Here, we want to get the value of x
To get the value of x, we need to know the kind of relationship that exists between the two given angles
Both angles lie on a straight line and that means they are supplementary
What this mean is that they add up to 180
(5x-7) + (3x + 27) = 180
5x -7 + 3x + 27 = 180
5x + 3x -7 + 27 = 180
8x + 20 = 180
8x = 180-20
8x = 160
x = 160/8
x = 20
Answer:
Step-by-step explanation:
Suppose x+3 < 0. Subtract 3 from both sides of the inequality.
x < -3
So, x+3 is negative when x < -3. When x>5,
x+3 > 8, which is positive, so the absolute value function has no effect.
|x+3| > 8

Answer:
-4.5
Step-by-step explanation:
-12-3x=x+6
-4x=18
x=-4.5
Answer:
H is 16.8
Step-by-step explanation:
If you multiply 5.6 times 3 you get 16.8 and then you add 5.6 because 0.56 times 10 equals 5.6
