Mathematics
1 answer:
mr_godi [17]4 years ago
4 0

\frac{1}{2} n - 10 = 27

let the number be 10 then half this number is \frac{1}{2} n and 10 less is

\frac{1}{2} n - 10

this is 27 meaning equal to 27 thus equation is

\frac{1}{2} n - 10 = 27

The steps to derive the quadratic formula are shown below:
prohojiy [21]

Answer:

\huge\boxed{\sf Option \ B}

Step-by-step explanation:

<h3>Step 3:</h3>

\displaystyle x^2+\frac{bx}{a} =\frac{-c}{a} --------------------(1)

<h3>The next step will be:</h3>
  • to find the b² for the expression on the left.
<h3>How to find b²:</h3>

Take the expression

\displaystyle x^2 + \frac{bx}{a}

<u>We can also write it as:</u>

\displaystyle (x)^2 + 2(x)(\frac{b}{2a} )

According to the formula a^2+2ab+b^2, the b of this expression is \displaystyle \frac{b}{2a}. So,

b² will be:

\displaystyle =(\frac{b}{2a} )^2\\\\=\frac{b^2}{4a^2}

So, we will add \displaystyle \frac{b^2}{4a^2} to both sides in Eq. (1)

For STEP 4, the equation will become:

\displaystyle x^2+\frac{bx}{a} + \frac{b^2}{4a^2} = \frac{-c}{a} + \frac{b^2}{4a^2}

\rule[225]{225}{2}

If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x

5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25

5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.

1 ton = 2000 pounds
0.05 ton = x

1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.
