Mr. Ellis is a teacher who tutors students after school. Of the students he
tutors, 30% need help in computer science and the rest need assistance in math.
Of the students who need help in computer science, 40% are enrolled in Mr.
Ellis’s class during the school day. Of the students who need help in math, 25%
are enrolled in his class during the school day. What percent of the
after-school students are enrolled in Mr. Ellis’s classes?

he kicked it up? is this the answer ?

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
