Step-by-step explanation:
Let's call x the lenght and y the height. The perimeter will be:
p = 2x + 2y = 10
When the lenght is halved and the height double we'll have:
p = x + 4y = 14
These 2 equations form a system of equations2 that can be solved and give as result:
y = 3
x = 2
Answer:
y=5/8
Step-by-step explanation:
(1/3)x =16 (x represents the total number of books he has)
x=48
Answer: If this is a trick question then he still has all 3 but if not he has 1
