Answer:

a. $\frac{\textbf{17}}{\textbf{4}}$

b. $\frac{\textbf{3}}{\textbf{8}}$

Step-by-step explanation:

a. $\textbf{3} \hspace{1mm} \textbf{+} \hspace{1mm} \textbf{1}\frac{\textbf{1}}{\textbf{4}}$

A mixed fraction of the form $a\frac{x}{y} = a + \frac{x}{y}$

$\therefore 3 + 1\frac{1}{4} = 3 + 1 + \frac{1}{4}$

$= 4 + \frac{1}{4}$

$= \frac{\textbf{17}}{\textbf{4}}$

b. $\textbf{2} \hspace{1mm} \textbf{-} \hspace{1mm} \textbf{1}\frac{\textbf{5}}{\textbf{8}}$

A mixed fraction of the form $-c\frac{a}{b} = - c - \frac{a}{b}$

$\therefore 2 - 1\frac{5}{8} = 2 - 1 - \frac{5}{8}$

$= 1 - \frac{5}{8}$

$= \frac{8 - 5}{8}$

$= \frac{\textbf{3}}{\textbf{8}}$

Hence, the answer.

Solve the equation square root 2x – 7 + x = 5 algebraically, and justify the solution set

yarga [219]

Answer: $x=4$

Step-by-step explanation:

$2x-7+x=5$

Group like terms:

$\left(2x+x\right)-7=5$

Simplify the arithmetic:

$3x-7=5$

Add 7 to both sides:

$3x-7+7=5+7$

Simplify the arithmetic:

$3x=5+7$

Simplify the arithmetic:

$3x=12$

Divide both sides by 3:

$\frac{3x}{3}=\frac{12}{3}$

Simplify the fraction:

$x=\frac{12}{3}$

Find the greatest common factor of the numerator and denominator:

$x=\frac{4\cdot 3}{1\cdot 3}$

Factor out and cancel the greatest common factor and the answer will be:

$x=4$
