Step-by-step explanation:
5-x<2(x-3)+5
5-x<2x-6+5
5-x<2x-1
6-x<2x
6<3x
x>2
Answer:
Volume= 540 ft^3
Step-by-step explanation:
Since volume= length times Width times height, you do 3 times 6 times 30= 540 ft^cubed.
Answer:
1 is to 4
Step-by-step explanation:
the factor is 1-4 meaning 32÷8 is 4 so having 1 would mean the other factor is 4
Answer:
r = √( s/4π)
Step-by-step explanation:
s = 4πr²
s/4π = 4πr²/4π
r² = s/4π
√(r²) =+/-√( s/4π)
r = √( s/4π) Because r is a radius of the circle , it should be positive.
Answer:

Step-by-step explanation:
Let's rewrite the left side keeping in mind the next propierties:


Therefore:

Now, cancel logarithms by taking exp of both sides:

Multiply both sides by
and using distributive propierty:

Substract
from both sides and factoring:

Multiply both sides by -1:

Split into two equations:

Solving for 
Add 4 to both sides:

Solving for 
Collect in terms of x and add
to both sides:

Divide both sides by e-2:

The solutions are:

If we evaluate x=4 in the original equation:

This is an absurd because log (x) is undefined for 
If we evaluate
in the original equation:

Which is correct, therefore the solution is:
