Your answer would be x = 6.

The only step is to divide by 2/3 on both sides of the equation.

Answer:

$A=\frac{65}{64}\ or\ A=1.015625$

Step-by-step explanation:

Given:

The expression is given as:

$2^{x-6}+2^{x}$

The equivalent expression to the above expression is given as:

$A\cdot 2^{x}$

Now, simplifying the original expression using the law of indices:

$a^{m-n}=\frac{a^m}{a^n}$

So, $2^{x-6}=\frac{2^x}{2^6}$ . The expression becomes:

$=\frac{2^x}{2^6}+2^x$

Now, $2^x$ is a common factor to both the terms, so we factor it out. This gives,

$=2^x(\dfrac{1}{2^6}+1)\\\\=2^x(\frac{1}{64}+1)\\\\=2^x(\frac{1}{64}+\frac{64}{64})\\\\=2^x(\frac{1+64}{64})\\\\=2^x(\frac{65}{64})\\\\=(\frac{65}{64})\cdot 2^x$

Now, on comparing the simplified form with the equivalent expression, we conclude:

$A\cdot2^x=(\frac{65}{64})\cdot 2^x\\\\A=\frac{65}{64}\ or\ 1.015625$

Therefore, the value of 'A' is $A=\frac{65}{64}\ or\ A=1.015625$

Find the slope of the line.

galben [10]

Answer:

0.5

Step-by-step explanation:

From the figure the line passes through the points (0,2) and (4,4).

The slope of the line that passes through the points $(x_1,y_1)$ and $(x_2,y_2)$ is always

$m=\dfrac{y_2-y_1}{x_2-x_1}.$

Therefore, the slope of the graphed line is

$m=\dfrac{4-2}{4-0}=\dfrac{2}{4}=\dfrac{1}{2}=0.5.$

Harry ate 3/8 of a large pizza. Aidan ate 1/2 of a small pizz. Harry said that since 4/8 is equivalent to 1/2,he and Aidan ate t

-BARSIC- [3]

Harry is incorrect. If Harry only ate 3/8 of the pizza and Aidan ate 1/2 of the pizza, Harry ate less pizza. Because 1/2 equals 4/8 and 4/8 is greater than 3/8, Aidan ate more pizza than Harry.

Hope this helps!!
