Answer:

No sir

Step-by-step explanation:

first you will try to get x by its self.

so were it says -5x = 3 you wanna do

+5 +5 on both sides to cancel out 5 so that would be

X = 8 because -5 + 5 is 0 which in this case will be left with X

you already have 8 so x = 8

Hopefully this helps

[Right Triangles Only] Pythagorean Theorem:
$\displaystyle a^2 + b^2 = c^2$

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Identify given variables.

a = 30

b = 3

c = x

Step 2: Find x

Let's solve for the general equation that allows us to find the hypotenuse:

[Pythagorean Theorem] Square root both sides [Equality Property]:
$\displaystyle \begin{aligned}a^2 + b^2 = c^2 \rightarrow c = \sqrt{a^2 + b^2}\end{aligned}$

Now that we have the formula to solve for the hypotenuse, let's figure out what x is equal to:

[Equation] Substitute in variables:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2}\end{aligned}$
Evaluate:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2} \\& = \boxed{ \sqrt{909} } \\\end{aligned}$

∴ the hypotenuse length x is equal to √909 and the number under the square root, our answer, is equal to 909.

What is 54 percent as a fraction in simplest form

atroni [7]

54% is 54 out of 100.
There for the numerator is 54 and the denominator is 100.

$\frac{54}{100}$

Now, both the top and the bottom can be divided by 2. So:

$\frac{54~divided~by~2}{100~divided~by~2}$ = $\frac{27}{50}$

$\frac{27}{50}$ can't be simplified anymore, therefore, 27/50 is 54% as a fraction.

~Hope this helped :)
