For which equation with x=3 be a solution?
Image above

B. x-2=1

Step-by-step explanation:

3-2=1

1=1

x = 3 is a solution for x - 2 = 1.

Step-by-step explanation:

Substitute x = 3 in all the equations.

x + 7 = 4

3 + 7 = 4

10 ≠ 4

x - 2 = 1

3 - 2 = 1

1 = 1

5 + x = 9

5 + 3 = 9

8 ≠ 9

8 - x = 11

8 - 3 = 11

5 ≠ 11

$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
