4x+30=2(x-10)
4x+30=2x-20
4x-2x= -30-20
2x= -50
x= -25

Answer:
I'd say Yev's description is best because it's the most specific to what it actually is in terms of science, while everyone else's descriptions are more like examples of different types and stages of energy, and where it could be found.
Hope this makes sense to ya :)
Answer:

And in order to solve this we have two possibilities:
Solution 1

And solving for T we got:


Solution 2
And the other options would be:


Step-by-step explanation:
For this case we can define the variable os interest T as the real temperature and we know that if we are 3 F more than the value of 98.6 we will be unhealthy so we can set up the following equation:

And in order to solve this we have two possibilities:
Solution 1

And solving for T we got:


Solution 2

Answer:

Step-by-step explanation:
Surface area of cylinder = 2πr(h + r)
Volume of cylinder = πr²h
Given that S.A = Volume of the cylinder, therefore, we have:
2πr(h + r) = πr²h
Radius (r) is given as 2.5 cm
height (h) = x cm
Input the values and solve for x
2πr(h + r) = πr²h
2πr(h + r) = πr(rh)
2(h + r) = rh (πr cancels πr)


Subtract 2x from both sides


Divide both sides by 0.5
