Answer:
5
Step-by-step explanation:
This means that 9/(2x-1)=15/(3x), so 27x=30x-15. This means that 3x=15, so x=5.
Step-by-step explanation:
Here we can see the both numbers are 7 with different powers so we can sum up the powers
Answer:
t=0 or t=44
Step-by-step explanation:
There are a few methods to do this, the most obvious being the use of the quadratic formula.
However, a quick check with a calculator or even your mind will reveal that 704 is divisible by 16. Thus we can solve this through factoring.
-16t(t-44)=0
Using the zero factor principle:
-16t=0 and so t=0
t-44=0 and so t=44
And thus we get the solution.
I believe It is A. infinitely solutions
