In an examination, 40% students passed in Mathematics, 45% passed in Science and 55% passed in English. 10% passed in Mathematics and Science, 20% in Science and English and 15 % in English and Mathematics.
a. Find the percentage of students who passed in all the three subjects.
b. Draw a Venn- diagram to illustrate the information.

$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

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
