84 2/3% to a fraction in lowest terms
RoseWind [281]

The evaluation of 84 2/3% to a fraction in its lowest term is \mathbf{ \dfrac{127}{150} }

<h3>What is a fraction?</h3>

Fractions are sections or parts of a whole. They are divided into two parts, the numerator, and the denominator.

From the given information, we are to convert a mixed fraction into its lowest terms. By doing that, we are to convert it to an improper fraction.

\mathbf{= 84 \dfrac{2}{3}\%}

\mathbf{= \dfrac{(84 \times 3)+2}{3} \%}

\mathbf{= \dfrac{254}{3} \%}

\mathbf{= \dfrac{254}{3} \times \dfrac{1}{100}}

\mathbf{= \dfrac{254}{300} }

Divide both the numerator and denominator by (2)

\mathbf{= \dfrac{127}{150} }

The solutions to (x + 4) ^2- 2 = 7 are​
Alona [7]

Answer:

x = -1, -7

Step-by-step explanation:

(x+4)^2 -2 = 7

(x+4)^2 -9 = 0 (Taking 7 to the other side)

(x+4)^2 - 3^2 = 0

Now use the difference of two squares rule

[((x+4)+3).((x+4)-3)] = 0

[(x+7).(x+1)] = 0

Now solve for x

x = -1, -7
