3√2x+1=15, then what is the value of x?<br><br> 0
kifflom [539]

Answer:

x = 7√2/3

decimal = 3.299831

Step-by-step explanation:

Subtract 1 from both sides

3√2x+1-1=15-1

Simplify

3√2x=14

Divide both sides by 3√2

3√2x/3√2 = 14/3√2

Simplify

x= 7√2/3

HELP FAST! Will give Brainiest i mainly need help on part C.
olchik [2.2K]
Part A: First, list multiples for each number. The multiples of 5 are: 5, 10, 15, 20, 25 30, 35, 40, 45, 50, 55, 60, etc. The multiples of 12 are: 12, 24, 36,48, 60, etc. The least common multiple is the first common multiple between the two, in this case being 60. The LCM of 5 and 12 is 60. 

Part B: SImilar to above, list all factors for each number. 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. 81: 1, 3, 9, 27, and 81. The greatest common factor is the highest common number, 9 in this case. The GCF of 72 and 81 is 9.

Part C: To rewrite, we need to take out the 9 by dividing. 72/9 is 8. 81/9 is 9. Therefore, we would get 9(8+9), to equal 153. Your answer here is 9( 8 + 9 ).  Hope this helped!

If a fraction can be written as a repeating decimal,only one digit can repeat over and over, without end. True or false?
steposvetlana [31]
True. it can only be written as one repeating number because eventually, a set of numbers would cancel out i think
