if someone has an 85.3% in honors science and gets a zero on a lab that is 20% of their grade, what is their new grade in honors science? (asking for a friend.. lol)

68.24 (oof, C)

Step-by-step explanation:

Put 85.3% as a real number: well, 85.3. Then, 20%of 85.3 is 17.06. Then 85.3-17.06 is 68.24.

Hope this helps you!! ; D

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
