Minus 9$ from the 13$ after you get the answer then double it you should come out with the correct answer

So to find the answer to this, you have to consider that \frac{1}{2} x + 9 = 13 - half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.

To solve this, first subtract 9 from both side, which leaves you with \frac{1}{2} x = 4 and \frac{1}{2} x is the same as \frac{1x}{2}, so to solve this, multiply both sides of the equation by two, resulting in x = 8. SO from this we can conclude that the weekly allowance is $8

-(m - 6) = 3m + 14<br> Multiply m- 6 by -1
Angelina_Jolie [31]

For this case we have the following equation:

- (m-6) = 3m + 14

We apply distributive property on the left side of the equation, taking into account that:

- * + = -\\- * - = +

So:

-m + 6 = 3m + 14

Subtracting 3m from both sides of the equation:

-m-3m + 6 = 14

Equal signs are added and the same sign is placed:

-4m + 6 = 14

We subtract 6 from both sides of the equation:

-4m = 14-6\\-4m = 8

We divide between -4 to both sides of the equation:

m = \frac {8} {- 4}\\m = -2

Thus, the solution of the equation ism = -2

ANswer:

m = -2

In the accompanying diagram of rectangle ABCD, diagonal AC is drawn, DE = 8, DE 1 AC, and m2 DAC = 55. Find the area of rectangl
Aneli [31]

Answer:

sin (55)  =  DE / AD

AD  =  DE / sin (55)

AD  =  8 / sin (55)

And  

tan (55) = DC / AD

tan (55)  = DC / [8 / sin (55) ]

DC  =  8 tan (55) / sin (55)    

AD * DC  =

[8 /sin (55) ]  [ 8 tan (55) / sin (55) ]   =    136 units^2
