Find the taxable income of a married couple with three children, who have a combined income of $62,000.
xeze [42]

Answer :

taxable income is $30,300

Step-by-step explanation:

Given

The combine income of the husband and wife = $62,000

Number of children the couple has = 3

In order to find out the taxable income for an U.S. family, the following formula is used

taxable income = total income - exemption deduction - standard deduction

We know the exemption deduction for a married couple with three kids fixed according to the U.S. government is $19,500.

And the standard deduction for a married couple with three kids fixed according to the U.S. government is $12,200.

Therefore,

taxable income = total income - exemption deduction - standard deduction

                         = $62,000 - $19,500 - $12,200

                         = $30,300

Thus the taxable income is $30,300.

How can one sixthx − 5 = one fifthx + 2 be set up as a system of equations?
s2008m [1.1K]
For problems like these, we can set both sides of the equation equal to y. This is because both sides of the equation are equal to each other. If we were to take the left side of the equation and set it equal to y, the right side would also be equal to y. Similarly, if we were to set the right side of the equation equal to y, the left side of the equation would also be equal to y. Setting both equations equal to y will produce two equations which can be used in a system of equations.

Thus, our answer is:
y = (1/6)x - 5
y = (1/5)x + 2

Please help me ASAP which figure shows the conjecture is false??
Tema [17]

The easiest place to start is with the answer. The 3 by 4 rectangle (upper right) is the answer. P = 2(L + W) = 2(4 + 3) = 2*7 is 14.


14 is less than 16.


Now lets find out why the others can't be true.


The upper left has an area of 12 (6*2). So the area is find.

P = 2 * (L + W) = 2* (6 + 2) = 16 This would support the conjecture so it is not the answer you want.


The lower left has an area of 12 and a perimeter of 2*(12 + 1) = 26. That supports the conjecture. So you don't want that one either.


The lower right does not have an area of 12. It cannot help us at all.
