Answer:
13.75
Step-by-step explanation:
3-7 is -4 because if you use a number line and start at three and go back 7 you will get -4
Given:
Consider the given expression is
To find:
The simplified form of the given expression.
Solution:
We have,
It can be written as
![[\because \log_ax+\log_ay=log_a(xy)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_ax%2B%5Clog_ay%3Dlog_a%28xy%29%5D)
![[\because \log_ax-\log_ay=log_a\dfrac{x}{y}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_ax-%5Clog_ay%3Dlog_a%5Cdfrac%7Bx%7D%7By%7D%5D)
Therefore, the simplified form of the given expression is 
.
Hey there! I'm happy to help!
Let's represent Tom's money as T, Ulrika's as U, and Harriet's as H. Let's put the information we have in a system of equations and solve the problem.
H=3U (Harriet has 3x as much as Ulrika)
H=T+304 (Harriet has 304 more than Tom)
T=U (Tom has same amount as Ulrika.)
We see that 3U and T+304 are equal because they both equal H.
3U=T+304
Since T and U are interchangeable because they are equal, we can replace the U with T to solve for T, which is also the answer for U.
3T=T+304
We subtract T from both sides.
2T=304
We divide both sides by 2.
T=152
This also means that U=152.
So, Ulrika has $152.
Have a wonderful day!
