Your equation for number one is 600,788,188/760,507,625 = x/100
After cross multiplying you will get 760,507,625x = 60,078,818,800
Then you will divide by <span>760,507,625 to isolate the varible to get 78.99 = x.

Your equation in number two is 80/143 = x/100 because when you subtract 143  by 63 you get 80, the amount of males in the room. Then you cross multiply to get, 143x = 8000. Then you would divide both sides by 143 to isolate the varible to get 55%</span>

What is the answer? -56×(78- 23)÷4?

Since (78-23) is in the bracket, you need to perform the operation of minus first.
that get you with
-56x(55)÷4
and then you just do it step by step
-56x55 = -3080
-3080÷4 = -770

Gross pay = $734
Take home percent of the gross pay = (453.10/734) * 100

From the above deduction, it can be easily concluded that the Take-Home percent of the Gross Pay is 61.73%. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.

Answer:

Step-by-step explanation:

x=81

y and z both equal 81

13+y+z=180

13+83.5+83.5

13+167
