Using your knowledge of cross products how would you solve for x in the following pair of equivalent fractions 7 over x equals 2/4

Use cross multiplication so you have

7/x = 2/4

multiple 7 and 4 to get 28 and multiply x and 2 to get 2x and set them equal to each other

so your new equation is 2x=28 and then you just need to solve for x

The answer is x=14

$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
