Well if it is 60 yd around the perimeter then you have the expression 2x+2y=60
The other expression is y=5x because it is 5 times the width. So when you plug that into the first expression you get 2x+10x=60 next is 12x=60 and x=5. so if x=5 plug that in so it is 10+2y=60. Take 10 away from 60 2y=50 and divide it by two so you get y=25. So y=25 and x=5
First, you have to find the equation of the perpendicular bisector of this given line.
to do that, you need the slope of the perpendicular line and one point.
Step 1: find the slope of the given line segment. We have the two end points (10, 15) and (-20, 5), so the slope is m=(15-5)/(10-(-20))=1/3
the slope of the perpendicular line is the negative reciprocal of the slope of the given line, m=-3/1=-3
step 2: find the middle point: x=(-20+10)/2=-5, y=(15+5)/2=10 (-5, 10)
so the equation of the perpendicular line in point-slope form is (y-10)=-3(x+5)
now plug in all the given coordinates to the equation to see which pair fits:
(-8, 19): 19-10=9, -3(-8+5)=9, so yes, (-8, 19) is on the perpendicular line.
try the other pairs, you will find that (1,-8) and (-5, 10) fit the equation too. (-5,10) happens to be the midpoint.
19
Step-by-step explanation:
9+10=19

Sergio will buy first! He is earning more than Lia per week, and it would take him about 34 weeks and he’d haves little money left over by that time :)
That might be truein a world where we follow rules. But no pg-13 means that it is more appropriate for children 13 and older. the pg refers to parental Guidance so any one under 13 might need their parent there with them.
