Hey there!

Let's write an equation given this information. We will use x to represent the number.

2(x-7)=5

Now, we use the distributive property to remove the parentheses.

2x-14=5

Now, we add 14 to both sides.

2x=19

We divide both sides by 2.

x=9.5

Therefore, our number is 9.5

I hope this helps!

Lin ran 2 3/4 miles in 2/5 of an hour. How far would Lin run in 1 hour?
hoa [83]
\begin{gathered} 2\frac{3}{4}=\frac{8+3}{4}=\frac{11}{4} \\ \frac{11}{4}mi\to\frac{2}{5}h \\ xmi\to1h \end{gathered}

Using cross multiplication:

\begin{gathered} \frac{11}{\frac{4}{x}}=\frac{2}{5} \\ x=\frac{11}{4}\cdot\frac{5}{2} \\ x=\frac{55}{8}mi=6\frac{7}{8}mi \end{gathered}

Convert a mixed number to a fraction:

how much cardboard would you need to construct a rectangular prism shaped box measuring 15 inches by 13 inches by 7 inches
givi [52]
We know that

[surface area]=2*[area of the base]+[perimeter of the base]*height

area of the base=15*13----> 195 in²

perimeter of the base=2*[15+13]----> 56 in
height=7 in
so
[surface area]=2*[195]+[56]*7-----> 782 in²

the answer is
782 in²
