Question

plz do these two question​

Answer 1

$\huge\bold{\mathbb{QUESTION}}$

Find the value of: $\;6x-1=2x+9.$

◯ $1{\dfrac{1}{2}}$

◯ $2{\dfrac{1}{2}}$

◯ $1{\dfrac{3}{12}}$

◯ $1$

$\huge\bold{\mathbb{TO\:FIND}}$

The value of $x.$

$\huge\bold{\mathbb{CONCEPT}}$

Linear Equations.

$\huge\bold{\mathbb{LET'S\:\,DO}}$

$6x-1=2x+9$

Combine the like terms.

$\implies 6x-2x=9+1$

$\implies 4x=10$

$\implies x={\dfrac{10}{4}}$

$\implies x={\dfrac{\cancel{10}}{\cancel4}}$

$\implies x={\dfrac{5}{2}}$

$\implies \underline{\boxed{\mathfrak\red{x=2{\dfrac{1}{2}} }}}$

$\huge\bold{\mathbb{HENCE}}$

$x=2{\dfrac{1}{2}}$

$\huge\bold{\mathbb{THEREFORE}}$

The value of $x$ is $2{\dfrac{1}{2}}.$

◯ $1{\dfrac{1}{2}}$

⊙ $2{\dfrac{1}{2}}\:$ ✓

◯ $1{\dfrac{3}{12}}$

◯ $1$

________________________________

$\huge\bold{\mathbb{QUESTION}}$

${\dfrac{7}{25}}={\underline{\:\:\:\:?\:\:\:\:}}\%$

$\huge\bold{\mathbb{TO\:FIND}}$

The fraction in percentage $(\%).$

$\huge\bold{\mathbb{CONCEPT}}$

In order to convert a fraction into percentage $(\%),$ we have to multiply the fraction with $100.$

$\huge\bold{\mathbb{LET'S\:\,DO}}$

$({\dfrac{7}{25}}\times 100)\%$

$= ({\dfrac{7}{\cancel{25}}}\times \cancel{100})\%$

$= (7\times4)\%$

$= \underline{\boxed{\mathfrak\red{28\%}}}$

$\huge\bold{\mathbb{HENCE}}$

${\dfrac{7}{25}}=28\%$

$\huge\bold{\mathbb{THEREFORE}}$

${\dfrac{7}{25}}$ expressed in percentage $(\%)$ is $28\%.$
