A breakfast stall at a market stays

Answer:

If it opens at 5:30, then it closes at 10:00 AM

If it opens at 6, then it closes at 10:30 AM

If it opens at 6:30, then it closes at 11:00 AM

If it opens at 7, then it closes at 11:30 AM

If it opens at 7:30, then it closes at 12:00 PM

After 12:00 PM, no one is going to have breakfast. So these are the only possibilities of the timing it will open. Either at 5:30, 6, 6:30, 7, or 7:30.

Select the correct choice below and fill in any answer boxes in your choice

So we need to solve:

$\frac{13}{y}+\frac{5}{y}=3$

First is important to note that both terms on the left side of the equation have a common factor because they are both divided by y. Then:

$\begin{gathered} \frac{13}{y}+\frac{5}{y}=\frac{1}{y}(13+5)=3 \\ \frac{13+5}{y}=\frac{18}{y}=3 \end{gathered}$

Then:

$\begin{gathered} \frac{18}{y}=3 \\ 18=3y \\ \frac{18}{3}=y \\ y=\frac{18}{3}=6 \end{gathered}$

So the solution is y=6. Then option A is correct and you need to write the 6 between the symbols { }.

If someone average free throw for basketball is 60% how many times in the next 50 tries will she make a free throw. Describe how

Anon25 [30]

So remember that percent means parts out of 100
60%=60/100=6/10
so every 10 throws she makes 6
how many 5 in 50?
50/10=5
answe ris 5
so 5 tens so therefor 5 sixes
5 times 6=30
answer is 30 throws
