This is solved by setting up two equations and then using one to answer the other.
The first step (use what is given to set up the two separate equations)
We are looking for two numbers, let us call them X and Y.
We are told that X + Y = 59
We are also told that (9 more than) 9+ (4times the smaller number) 4Y is the bigger number X
Then we combine that into 9+4Y=X
so we now have two separate equations and we can use one to solve the other. Everywhere we have X in the first equation, we will fill in with the second equation
(9+4Y) +Y = 59 [then combine like terms]
9+5Y=59 [subtract 9 from both sides]
5Y=50 [divide both sides by 5 to isolate the Y]
Y=10 [now plug this into either equation to solve for X]
9+4(10)=X
9+40=X
<u><em>49=X and 10=Y</em></u>
The dad had 6 more hours remaining to drive
Answer:
1. is not
2. increase
3. remain the same
Step-by-step explanation:
3 plus 11/10 (mix number, you can get it by simplifying 300/100=3 with 11/100 left over)
311/100 (improper fraction=a fraction where the numerator is bigger than the denominator, you get it by just taking the last decimal place which is a houndredth here so you take the whole thing over 100 basically)
I believe the answer is 7.94
the hundredth is the 4
