\bf 3.8888888\overline{8}\\\\
-------------------------------\\\\
x=3.8888888\overline{8}\qquad thus\qquad 
\begin{array}{llcll}
10x&=&38.888888\overline{8}\\
&&\downarrow \\
&&35+3.8888888\overline{8}\\
&&\downarrow \\
&&35+x
\end{array}
\\\\\\
10x=35+x\implies 9x=35\implies x=\cfrac{35}{9}

the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.

Solve the equation square root of x plus three plus four equals five for the variable. Show each step of your solution process
alekssr [168]

Answer:

x=-2

Step-by-step explanation:

The given expression is

\sqrt{x+3}+4=5

We group the constant terms on the right hand side to obtain;

\sqrt{x+3}=5-4

\Rightarrow \sqrt{x+3}=1

We square both sides of the equation to remove the square root.

\Rightarrow (\sqrt{x+3})^2=1^2

x+3=1

This will simplify to;

x=1-3

x=-2

6c - (3 – 3c) = 24<br> Solve equation step by step
kap26 [50]

Hi there! :)

\large\boxed{c = 3}

6c - (3 - 3c) = 24

Distribute the negative sign with terms inside the parenthesis;

6c - (3) - (-3c) = 24

6c - 3 + 3c = 24

Combine like terms:

9c - 3 = 24

Add 3 to both sides:

9c = 27

Divide both sides by 9:

c = 3.
