Answer:
4
Step-by-step explanation:
The least common denominator (LCD) for 1/12 and 3/4 is b. 12
<span>2x + 5 = 27
subtract 5 to both sides
2x + 5 - 5 = 27 - 5
simplify
2x = 22
divide both sides by 2
2x/2 = 22/2
simplify
x = 11
answer is </span><span>11 (second choice)

Answer:
The best choice is y = 82.1
Step-by-step explanation:
Just simplify both sides of the equation, then isolate the variable.
Which makes it's exact form y= 34^5/4 and when converting it to decimal form it becomes y = 82.1
