x=-15/8 or -1 7/15 OR x=-5/3 or -1 2/3

Step-by-step explanation:

Subtract 15 from both sides

8x=-15

Divide 8 on both sides

Now you get your answer

x=-15/8 or -1 7/15

OR

Combine like terms

9x+15=0

Subtract 15 from both sides

9x=-15

Divide 9 from both sides

x=-15/9

Simplify

x=-5/3 or -1 2/3

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

$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
