Answer:
No
Step-by-step explanation:
5 × 6 = 30 - 5 = 25
5 × 2 = 10 - 1 = 9
D. 4/5. Just have to figure out what is left. so 5/5-1/5=4/5
Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8
Meaning that the two numbers are -8 and 1.
The first step because 1 dollar and 60 cents is not (1.6)= 2 dollars and 5 cents
