Answer:

(A) 12

Step-by-step explanation:

First, lets define the number as x.

"8 times the difference between a number and 6 is equal to 4 times the number" is translated into "8(x - 6) = 4x"

8(x - 6) = 4x

8x - 48 = 4x

4x = 48

x = 12

Answer:

The correct answer is option A.  12

Step-by-step explanation:

It is given that,8 times the difference between a number and 6 is equal to 4 times the number.

<u>To find the number</u>

Let x be the number, then we can write,

8 * (x - 6) = 4x

8x - 48 = 4x

8x - 4x = 48

4x = 48

x = 48/4 = 12

Therefore the correct answer is option A.  12

81^5=3^x What does “x” equal?
Lynna [10]

Answer:

x =2 0

Step-by-step explanation:

{81}^{5}  =  {3}^{x}

We know that 3^4 = 81. So :

=  >  { ({3}^{4}) }^{5}  =  {3}^{x}

=  >  {3}^{4 \times 5}  =  {3}^{x}

=  >  {3}^{20}  =  {3}^{x}

Here both the Right hand side & Left hand side has same base i.e. have 3 as base in both the sides.

So , eliminating the base gives :-

x = 20

Can someone help me please ASAP
zmey [24]

Answer:

<h2>140°</h2>

solution,

Let <DEF= x°

<CDE= 2x°

<BAF= 90°

The sum of interior angle of hexagon= 720°

<A + <B + <C + <D + <E +<F = 720°

90 + 145 + 115 + 2x + x + 160 = 720 \\ 510 + 3x = 720 \\3x + 510 = 720 \\ 3x + 510 - 510 = 720 - 510 \\ 3x = 210 \\  \frac{3x}{x}  =  \frac{210}{3}  \\ x = 70 \: degree

Again,

< \: cde = 2x \\  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  = 2 \times 70 \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 140 \: degree

Hope this helps...

Good luck on your assignment..
