Answer:
Step-by-step explanation:
6x-1+3x+5x+3+4x+8+5x+5=360 degree(sum of exterior angle of a pentagon is 360 degree)
23x+15=360
23x=360-15
x=345/23
x=15
therefore the value of x is 15 degree.
You would divide 4.6 from both sides of the inequality symbol to get x standing alone.
Answer: -7
Step-by-step explanation: x=3 and y=2
1. 700 calories
2. Half a serving
3.x=serving
350x=calories
For this case we have the following equation:

Where,
w: The weight of a spring in pounds
E: the energy stored by the spring in joules.
Substituting values we have:

Making the corresponding calculation:
Answer:
the approximate weight of the spring in pounds is:
