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>
YES IT IS RIGHT.YOU ARE RIGHT
Answer:
If the balance is growing exponentially the balance after 45.4 months will be $44,925.94.
Step-by-step explanation:
The exponential growth equation is:
Compute the value of f (x) for <em>x</em> = 45.4 as follows:
Thus, if the balance is growing exponentially the balance after 45.4 months will be $44,925.94.
Answer:
29 Minutes
Step-by-step explanation:
The original speed is given in miles per hour (like a car), but the answer is asking for miles per minute, so we must convert the speed into miles per minute first. To do this, we set up this equation: 
which equals 
. We can then divide the desired number of miles by the speed in miles per minute. Here is the eqaution for this 
. The miles cancel and you are just left with 29.1 minutes after you divide 4.9 by 0.168333333. Hope this helps!
