Answer:

x=6

Step-by-step explanation:

In a rectangle, all angles should be 90 degrees so, you need to solve the equation in the rectangle to 90 degrees. To do this, you first subtract 12 from 90 to get 78 then proceed to divide that by thirteen to isolate the x. Doing all of this should leave you with the answer x=6.

Hannah was asked to make d the subject of the formula<br> d-7=4d+3/e<br> Finish her question.
tigry1 [53]

Answer:

d = \frac{-1}{e} - \frac{7}{3}

Step-by-step explanation:

In order to make d the subject of the formula, you need to isolate it.

- You started with d-7 = 4d + 3/e

- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...

d - 7 = 4d + 3/e              This will leave you left with -3d - 7 = 3/e

-4d     -4d                          

- Then move over the -7 by adding 7 to both sides...

-3d - 7 = 3/e              This will leave you left with -3d = 3/e + 7

     +7          +7

- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...

d = \frac{3}{-3e} -\frac{7}{3}

- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be

d = \frac{-1}{e} - \frac{7}{3}
