Answer:
1.8 and 14.3
Step-by-step explanation:
Our equation is a quadratic equation so we will use the dicriminant method
- Let Δ be our dicriminant
- a=1
- b= -16
- c= 25
- Δ= (-16)²-4*25*1=156≥0
- so we have two solutions : x and y
- x= (16-)/2= 1.7555≈ 1.8
- y=(16+)/2=14.244≈ 14.3
Answer:
Step-by-step explanation:
We'll need the actual prices of one of the objects to figure it out...
but I've worked it out here in relation to each object....
Marker = 1/3 x cost of the pen
Marker = 1/3 x 1/3 x cost of book = 1/9 x cost of the book
Marker = 1/3 x 1/3 x 1/3 x cost of game = 1/27 x cost of the game
This probably isn't what you're looking for, but maybe it'll help?
