The answer:
_____________________________________________
x = (⅔)y ;

y = 3x/2.
_____________________________________________
Given:

x + (⅓)y + x - (2/4)y - x = (3/6)y ;
______________________________________

Take the: x + x - x = 1x + 1x - 1x = 2x - 1x = 1x = x ;

and rewrite:

x + (⅓)y - (2/4)y = (3/6)y ;
_______________________________
Note that: (2/4)y = (½)y ;

and: (3/6)y = (½)y ; so;
___________________________
Rewrite as:
____________________________
x + (⅓)y - (½)y = (½)y ;

Add "(½)y" to EACH SIDE of the equation;
_________________________________
x + (⅓)y - (½)y + (½)y = (½)y + (½)y ;

to get: x + (⅓)y = y ;

x = 1y - (⅓)y = (3/3) y - (1/3)y - [ (3-1)/3] y = (⅔)y ;

So: x = (⅔)y ;

In terms of "y" ;

Given: (⅔)y = x ; Multiply each side of the equation by "3" ;

3*[(⅔)y] = 3*x ;

to get: 2y = 3x ;

Now, divide EACH SIDE of the equation by "2" ; to isolate "y" on one side of the equation; and to solve for "y" (in terms of "x"):

2y / 2 = 3x / 2 ;

to get:

y = 3x/2 ;

A class has 40 students. The teacher asks how many students in the class have siblings and finds 3/10 of the students have sibli

leva [86]

Answer:

12 students

Step-by-step explanation:

First, find the percentage of how many students have siblings:

3/10 = 0.3 = 30%

40 * 0.3 = 12

This means that 30% of this class are 12 students. These 12 students have siblings.

Hope this helps!
