The total number of students in your classroom are 36 students. 5/12 of the 36 students are girls.
This expression can be represented by the equation:
5/12 * 36 = 15.
So, 15 students are girls in your classroom.
Hope this Helps! :)
A: 2.5 pounds= 2.5
B: 2.5 pounds= 1.63
C: 2.5 pounds= 1.25
Lowest to highest is C, B, A
Direct relationship
It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)
1) Look for common factors. You see that y^2 is a factor of every term so you can remove it to get
... = (y^2)(3x^2 -2x -8)
The quadratic in x can be factored by your favorite method. There is one called by various names that has you look for factors of (3)(-8) that add to (-2). When the quadratic is written as ax^2+bx+c, you're looking for factors of the product "ac" that add to "b". Of course, you know that
... -24 = -24*1 = -12*2 = -8*3 = -6*4
the last factor pair shown here has a sum of -2, so our factorization is
... = (y^2)(3x -6)(3x +4)/3 . . . . . the "a" coefficient is repeated in each factor (at first), then divided out
... = (y^2) (x -2) (3x +4)
2) You recognize this expression to be of the form
... (x +a)^2 = x^2 +2ax + a^2
where a=5. As a result, you know the factorization is
... = (x +5)^2
3) You recognize this expression to be the difference of squares, so you know the factorization is
... a^2 - b^2 = (a -b)(a +b)
where a=x and b=6. As a result, you know the factorizatin is
... = (x -6) (x +6)
