If 5+ 20 -22-3х - 10.2-2x+5, what is the value of х?
Elodia [21]

Answer:

<h2>3</h2>

Step-by-step explanation:

5+20\cdot2^{2-3x}=10\cdot2^{-2x}+5\qquad\text{subtract 5 from both sides}\\\\20\cdot2^{2-3x}=10\cdot2^{-2x}\qquad\text{divide both sides by 10}\\\\2\cdot2^{2-3x}=2^{-2x}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\2^{1+2-3x}=2^{-2x}\\\\2^{3-3x}=2^{-2x}\iff3-3x=-2x\qquad\text{subteact 3 from both sides}\\\\-3x=-2x-3\qquad\tex\qquad\text{add}\ 2x\ \text{to both sides}\\\\-x=-3\qquad\text{change the signs}\\\\x=3

Use the interactive number line to find -3.2 - 4.
SVEN [57.7K]

Answer:

-7.2

Step-by-step explanation:

Since -3.2 is the first number, this will be the starting point in the number line.

Since we are subtracting, we are going to go 4 units to the left.

-3.2 - 4 = -7.2

Best of Luck!

\dfrac{(a+b)(a-b)}{a+b}  =  12

--------------------------------------------------
 Crossed out common factors, (x + a) :
