A. X+Y=50 y=x+20

B. 50-x=x+20 x=15 minutes

C. No, We know however much time Ted spends on the butterfly he spends 20 mins more on breast stroke. If he spends 45 mins on butterfly then he must spend 45+20= 65 mins on breast stroke. BUT we already know that he only spends 50 mins total, so it’s not possible

Find the unit rate: 6 and 2/5 rotations in 2 and 2/3 seconds.

GrogVix [38]

I'd suggest you write "6 2/5," not "6 and 2/5."

6 2/5 rotations
-------------------- =
2 2/3 seconds

32
---
5 32 3
------- = ------ * -----
8 5 8 Reduce that 32/8: obtain 4.
---
3

Then we have

4(3)/5, or 12/5 rotations per sec.

Can anyone help me with this math problem?

wariber [46]

Lemme give you a cheap answer, by simply using the "compound interest formula", which is what that is, 2% compounded yearly

thus $\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\qquad 
\begin{cases}
A=\textit{current amount}\to&\boxed{y}\\
P=\textit{original amount deposited}\to &\$23000\\
r=rate\to 2\%\to \frac{2}{100}\to &0.02\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{per year, meaning once}
\end{array}\to &1\\

t=years\to &\boxed{x}
\end{cases}$

plug in those values, and simplify
