It takes the son one and half hours to clean the house. To find this you need the equations F+S=2 and F+1=S. (F=father and S=son) You take the F+1 and substitute it in for S in F+S to get F+(F+1)=2. Then you combined like factors, 2F+1=2, and simplify to get F=.5hr. After this you plug .5 in to F+1=S to get (.5)+1=S, meaning it takes the son 1.5 hour to clean the house.
Answer:
It is -7
Step-by-step explanation:
Break the parentheses and it will become 5.1 + -12.1 which will equal -7.
The correct answer is only A, because you need the tenths place to be greater than the number on the left, and not just the hundredths place.
P.S. Even though I'm a beginner, I took Multi-Variable calculus in 12th grade.
