Problem #11:
Twice a number (n) decreased by 5 is at least 11.
2n - 5 is = to or greater than 11.
2n - 5 is = to 11 comes out as 2n = 11 + 5, or 2n = 16, or n = 8.
If n = 8 or is greater than 8, 2n=5 will be at least 11.
Please, start work on the problems you haven't yet done. I'd be happy to comment on your own work and help you bring the solution to conclusion.
Answer:
27
Step-by-step explanation:
54/27=2
81/27=3
135/27=5
X should be 1/2
The way I solved this was by viewing 1/8. I grabbed 8 from the equation and did 8^(1/3) which got me 2. In addition both 1/8 and 1/2^3 in decimal form are both 0.125
Answer:
225 km^2
