Answers

Answer 1
Answer: 3x + 5y = 54

y = x - 2
________________________________________________________
3x + 5(x - 2) = 54
3x + 5x -10 = 54
8x = 64
x = 8

y = x - 2
y = 8 - 2
y = 6

You earn $50,000 dollars per year and the federal tax rate is 10%. Your gross income isa. $5,000
b. $10,000
c. $45,000
d. $50,000

Answers

Answer:

d. $50,000

Step-by-step explanation:

Since, gross pay is the payment before charging any tax or deduction.

Given,

The original earning = $ 50,000,

Percentage of federal tax rate = 10%,

So, the gross income would be $ 50,000

Note : the gross income after deduction of any taxes is called total taxable income.

Hence, OPTION d is correct.
A because if you multiply 50,000 by .10 (10%) you'll get 5,000

Can you go to grandmas estate and measures 8 inches across by 2 inches high if the actual stadium measures 500 feet across which equation can be used to find ex the height of the stadium in feet

Answers

Answer:

Step-by-step explanation:

Given that,

The estate is estimated as 8in across and the actual measure across is 500 ft

Then, this shows that

8in represent 500ft on scale

Then, divide both sides by 8

1in will represent 62.5ft

Now, we are told that the height of the stadium is estimated as 2inches, so what is the real value in ft

Since, 1in =62.5ft

Then, multiply both sides by 2

Therefore, 2in=125ft.

The height of the stadium in feet is 125ft

Factor completely 5v^2+5v-100
