A=1/2bh for b<img src="https://tex.z-dn.net/?f=a%3D1%2F2bh%20for%20b" id="TexFormula1" title="a=1/2bh for b" alt="a=1/2bh for b"

valkas [14]

Times both sides by 2
$2A=bh$
divide both sides b h
$\frac{2A}{h}=b$
$b=\frac{2A}{h}$

Eight times a number is the same as 30 less than 5 times the number. Find the number?

Charra [1.4K]

Answer:

x = -10

Step-by-step explanation:

We just have to translate the problem correctly

>8 times a number is the same

this tells me that

$8x = ...$

>as 30 less than 5 times the number.

$... = 5x - 30$

Now set them equal to eachother

$8x = 5x - 30$

Now isolate the variable x

$8x - 5x = 5x - 5x - 30\\3x = -30\\x = \frac{-30}{3} = -10$

140 subtracted from the square of a number the result is three times the number find the negative solution

natima [27]

Answer:

$Suppose~that~the~number~is~x.\\According~to~question,\\x^2-140=3x\\or, x^2-3x-140=0\\From~the~quadratic~formula,\\x = \frac{-(-3)+\sqrt{(-3)^2-4(1)(-140)} }{2(1)} ~and ~x= \frac{-(-3)-\sqrt{(-3)^2-4(1)(-140)} }{2(1)} \\or, x = \frac{3+\sqrt{9+560} }{2}~and~x=\frac{3-\sqrt{9+569} }{2}\\or, x = \frac{3+\sqrt{569} }{2}~and~x=\frac{3-\sqrt{569} }{2}\\So,~the~required~negative~number~is~\frac{3-\sqrt{569} }{2}.$
