Instead use WolframAlpha.com for math questions  I would paste the answer but a cretinous fop has "disabled" that feature by javascript -- which is trivial to circumvent but I won't bother with the time.

How to do linear equations 27, 28,28,30
Mekhanik [1.2K]
#27.  
First cross multiply
2 (2a-3) = 3 (a-1)
next use the distribute property on both sides
4a - 6 = 3a - 3
combine like terms, subtract 3a from both sides and add 6 to both sides
a = 3

#28
cross multiply
3x = 4, then divide both sides by 3
x = 4/3

#30
add 1/4 to both sides
3/x = 1/2 + 1/4, find a common denominator for the right side fractions
3/x = 2/4 + 1/4 = 3/4
therefore, x = 4

Reposting because nobody will help me..
Llana [10]

Answer:

B

Step-by-step explanation:

18 = 2 * 3 * 3 = 2 *3²

18*3^{(n+2)} = 2*3^{2}*3^{n+2}\\\\

                = 2*3^{2+n+2}\\\\= 2*3^{n+4}\\\\= 2(3)^{n+4}

Hint:

a^{m}*a^{n} = a^{m+n}

HELP PLEASE my teachers always force me to turn on my camera during class unless I have a valid excuse can anyone give me a crea
allsm [11]

Answer: My internet connection is not good enough.

Step-by-step explanation: This one may be pretty commonly used but also a common problem people always have and it's pretty unavoidable. Tell her that the call\meeting gets super laggy and then ends up freezing and that doing it over voice is a better option for you so you can get the best learning experience or something like that. Basically pretend you care until he\she believes it.

Good luck <3 Let me know if you need another!
