So x times y=15 x+y=12 solve x+y=12 subtract x from both sides y=12-x subsitute xy=15 x(12-x)=15 distribute 12x-x^2=15 subtract (12x-x^2) from both sides 0=x^2-12x+15 use quadratic formula which is x= where you have 0=ax^2+bx+c so a=1 b=-12 c=15 subsitute x= x= x= x= x=6+/- x=6+ or 6- or aprox x=10.5826 or 1.41742 the numbers are 10.5826 and 1.41742
Step-by-step explanation: The loop is 1.2 miles, and the total walk is 3.6 miles. You want to find out how many laps are in the 3.6 miles. This can be found using division. 3.6/1.2= the number of 1.2 mile laps inside the 3.6 mile walk, which is 3 laps. hope this helped!
