4+ 7y + 12 = 7y + ?

7y + 16

Step-by-step explanation:

All you have to do for this question is combine like terms. Since 7y is the only number with a variable (y), you cannot combine this with anything else.

The only thing left to do now is to combine 12 and 4. This equals 16. Therefore, the simplified version of this equation is 7y + 16.

I hope this helps! :)

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
