#1: y= 0.5+3 x
which means that x= y/3 - 0.5
#2: y= 3(0.5) x
which means that y= 1.5 x
that means x = y/1.5
Hope it can help
Answer:
Imagine that the number that we are looking for is x
We know that:
x/5 - 78 = 9
x/5 = 9 + 78
x/5 = 87
x = 87 . 5 = 435
So the number we need is 435
The correct answer is x≈1.01
You're welcome. ;)
