Answer:
Taking that you didn't provide any other information about the values of x..
The only plausible answer, which probably isn't your case but still can be valid out of context is 19.
Step-by-step explanation:
"X" is 10 in Roman numbers.
9 + 10 = 19
(But I suppose that you had more details to the question that you didn't yet share :) )
OR.. the answer might be an algebraic expression..
<u><em>"9+x" years old.</em></u>
15-1/6n=1/6n-1
First, lets multiply both sides by 6 so that n is a whole number:
90-n=n-6
now you group like terms on each side, to do this you add n to each side and add 6 as well so it becomes:
96=2n
Now divide both sides by 2 so you have 'n' on one side and it is:
48=n
Hope this helps :)
Answer:
x= -5
Step-by-step explanation:
Divide each term by
5
and simplify.
Now Steve, you can tap these into your calculator one by one,
get all the quotients, and mark the ones that are 4.2, all in about
3 minutes.
There are three (3) of them in the list.
One of them is 'C'. 27.3 ÷ 6.5 = 4.2
Now pick up your calculator and find the other two. You can do it !
