Answer:
Original Price = 160
Sale Price =40
Step-by-step explanation:
Let Original Price be x and Sale Price be y
y=1/4 of x (Equation 1)
x=120+y (Equation 2)
Put value of x from equation 2 in equation 1
y= (1/4)*(120+y)
y=120/4 + y/4
y-y/4=30
3y/4=30
y=30*4/3
y=40
Put value of y in Equation 2
x=120+40
x=160
Yes but if you need it in mixed number form it’s 1 1/3
A (−3, 1) and B (3, 4)
2 Let A have coordinates (x1, y1). Let (x1, y1) = (−3, 1).
3 Let B have coordinates (x2, y2). Let (x2, y2) = (3, 4).
4 Find the length AB by applying the
formula for the distance between
two points.
AB = "(x2 − x1)2 + (y2 − y1)2
= "[3 − (−3)]2 + (4 − 1)2
= "(6)2 + (3)2
= !36 + 9
= !45
= 3!5
= 6.71 1
