Plug n = 18 and r = 6 into the nCr combination formula

n C r = (n!)/(r!*(n-r)!)
18 C 6 = (18!)/(6!*(18-6)!)
18 C 6 = (18!)/(6!*12!)
18 C 6 = (18*17*16*15*14*13*12!)/(6!*12!)
18 C 6 = (18*17*16*15*14*13)/(6!)
18 C 6 = (18*17*16*15*14*13)/(6*5*4*3*2*1)
18 C 6 = 13366080/720
18 C 6 = 18564

Answer: 18564

Solve the rational inequality x-2/x + x+2/x+3 &lt; 3/2 represent your answer using a number line and using interval notation
Firdavs [7]

Answer and explanation:

To solve the inequality x-2/x + x+2/x+3 < 3/2 we have to first simplify the expressions on the left side of the inequality sign. And so we multiply x by the expressions on the left side to eliminate fractions:

=x(x-2/x)+x(x+2/x)+x(3)< 3/2

=x-2+x+2+3x < 3/2

=5x < 3/2

x < 3/2/5

x < 3/2×5/1

x < 15/2

x < 7 1/2 or 7. 5

Mrs. Williamson had 18 students in her homeroom at the beginning of the school year and 24 students at the end of the year. What
jarptica [38.1K]

Answer:

25%

Step-by-step explanation:

An easy way to figure this out is just by dividing the initial amount of students (18) by the current amount of students (24), and then subtracting 1.

So, 18/24 = 0.75 (aka 75%), and  1 - 0.75 = 0.25 (aka 25%)
