I forgot how to find x

Mathematics
1 answer:
GuDViN [60]3 years ago
6 0
You would do 2x-3+x+3x-15=360
combine like terms which then gives you 
5x-18=360 then you would add 18 to both sides giving you
5x=378 
and then you divide by 5 on both sides which will then give you your answer x=?

The equation y=2.54x gives the length y in centimeters corresponding to a length x in inches. What is the length in centimeters
bija089 [108]
The equation given in the question is
y = 2.54 x
In this equation, x is in cm and y is in inches
Size of the ruler = 1 foot 
                          = 12 inches.
Putting the value of 12 inches in the equation, we get
y = 2.54x
   = 2.54 * 12
   = 30.48 cm
From the above deduction, we can conclude that the length of the ruler is 30.48 cm. I hope that this is answer that you were looking for and the answer has come to your desired help.

SOMEONE HELP<br> PLS EXPLAIN STEP BY STEP WHAT TO DO IM SO CONFUSED
Kruka [31]

Answer:

  x = log(33)/(3·log(2))

Step-by-step explanation:

The relevant logarithm relation is ...

  log(a^b) = b·log(a)

__

Taking the logarithm of both sides of your equation gives ...

  2^(3x) = 33

  log(2^(3x)) = log(33)

  (3x)·log(2) = log(33)

The coefficient of x is 3·log(2). Dividing by that gives the value of x:

  x = log(33)/(3·log(2))

  x ≈ 1.51851/(3·0.301030) ≈ 1.6814647
