Answer:
x = -11
Step-by-step explanation:
First, add three to both sides on the equation. Then, your equation becomes 55= -5x. Finally, divide both sides by -5 to get -11 = x. So, x equals -11. Hope this helps!
Answer:
22,-15 ................ maybe
Answer:
The answer would be B: 8 ones, 4 tenths, and 5 hundredths.
Explanation:
First, you would have to use the equation: 1.57 + 6.88 = ?
Do the math, and 1.57 + 6.88 = 8.45
Now look at the answer choices. You can automatically get rid of every answer choice but B because none of them have an 8 in the ones place.

Answer:
1: 30 degrees
Step-by-step explanation:
In Physics, we have the law of reflection. This law states that when light rays hit the smooth surface of mirror or any smooth polished surface, the angle of incidence is equivalent to the angle of reflection.
Mathematically:
Angle of incidence = Angle of reflection
From the above question, the angle of incidence is on a smooth plane mirror = 30°
Since:
Angle of incidence = Angle of reflection
30° = 30°
Therefore, based on the law of reflection, the Angle of reflection = 30°
