Answer: x = -1
Step-by-step explanation:
i assume you mean
5x-(5x+3) = -1/3(12x+21)
lets start with the left
-(5x+3) can be turnd into -5x-3
now it is
5x-5x-3 and that can be just -3
now lets go to the right and get rid of the 1/3
we see the 3 at the bottom of 1/3, and (12x+21) can be factored with 3
so 1/3 x 3(4x+7) is what we get
1/3 x 3 cancels out so we are left with
-3 = (-4x-7)
lets try to get -4x by itself
if you move -4x to the left, turning it into 4x, and move -3 to the right, turning it into 3, you get 4x = -7 +3
-7 +3 = -4
4x = -4
devide by 4
4x/4 = -4/4
x = -1

Answer: 57
Step-by-step explanation:
Bowtown to Cliffton is 20 miles and clifttion to Aranville is 37 miles
20 + 37 is 57 miles
The value of the expression log₄2 is 1/2.
The logarithmic function is the inverse of the exponential function. This means that the logarithm of a given number, say x, is the exponent to which another fixed number that is the base b, must be raised, so as to produce that number x.
Log a to the base b can be written as- log a/ log b.
Moreover, log = k log a, for all non negative values of a
Here, we are given a logarithmic expression- log₄2
We can expand this as-
log₄2 = log 2/ log 4
= log 2/ log
= log 2/ 2 log 2
= 1/2
Thus, the value of log₄2 is 1/2.
