8 0

Answer:

Explanation:

Solve for n:

Subtract 8 on both sides.

5n + 8 = 30

-8 -8

Divide by 5 on both sides.

5n = 22

--- ----

5 5

Getting a solution of 4 2/5.

n = 4 2/5

Check:

5(4 2/5) + 8 = 30

22 + 8 = 30

30 = 30

How do i do 13 A and 13 C

Paladinen [302]

$\bf c^2=a^2+b^2\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\ side\\
b=opposite\ side\\
-------------\\
\textit{since they're equal}\\
\textit{let's call them "u"}\\
a=u\qquad since\qquad a=b\\
b=u\\
--------\\

c=850
\end{cases}
\\ \quad \\
850^2=u^2+u^2\implies 850^2=2u^2\implies \cfrac{850^2}{2}=u^2
\\ \quad \\
\sqrt{\cfrac{850^2}{2}}=u\implies 
\begin{cases}
\sqrt{\cfrac{850^2}{2}}=a\\\\
\sqrt{\cfrac{850^2}{2}}=b
\end{cases}$

now, for 13c
how much square feet will be covered? square feet means, Area,
namely, what is the area of that triangle?

well, now you know what sides "a" and "b" are,
area of a triangle is 1/2 b * h

Indicate the equation of the given line in standard form.

Ganezh [65]

Since the slope stays the same as it's parallel, we have y=(3/4)x+b. Plugging (2,-1) in, we get -1=3*2/4+b=6/4+b=1.5+b. Subtracting 1.5 from both sides, we get -2.5=b and our equation being y=(3/4)x-2.5 (since in y=mx+b, y and x remain as variables)
