Three balls will be needed. You will need 70 pieces of the 40 cm string so 70 multiplied by 40 equals 2800. Next you need to convert the 2800 cm into meters and 2800cm= 28 meters, so if each ball of string is 10 meters long you will need 3 of them which will give you 30 meters so you will have enough with a little extra. Hope this helped!

The slope of this equation is 2/3
The answer is: " 8 " .
________________________________
Explanation:
________________________________
Let "x" represent the "original number".
2(x - 3) = 6 + (1/2)x ; Solve for "x" ;
______________________________________
Multiple the ENTIRE EQUATION (both sides) by "2" ; to get rid of the fraction:
2*{2(x - 3) = 6 + (1/2)x} ;
to get:
4(x - 3) = 12 + x ;
___________________________
Let us expand the "left-hand side" of the equation:
_____________________________________________
Note the "distributive property of multiplication" :
_____________________________________________
a(b - c) = ab - ac ;
a(b +c) = ab + ac ;
______________________________________________
So; "4(x - 3)" = 4*x - 4*3 = 4x - 12 ;
______________________________________________
Rewrite the equation:
_______________________________________________
4x - 12 = 12 + x ;
Subtract "x" from EACH side of the equation; and Add "12" to EACH SIDE OF THE EQUATION;
______________________________________________
4x - 12 - x + 12 = 12 + x - x + 12 ;
to get:
______________________________________________
3x = 24 ;
_____________________________________________
Now, divide EACH side of the equation by "3" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_____________________________________________
3x/3 = 24/3 ;
_____________________________________________
x = 8 .
