Simplify radical expressions with root inside the root

Full solution

Q.

a=8 \div b

\newline

hich number below would make the inequality

7-2 x \leq 15

true?

Solve for b: First, let's solve for $b$ in the equation $a=\frac{8}{b}$ . $\newline$ $a = \frac{8}{b}$ $\newline$ To find $b$ , we can multiply both sides by $b$ and then divide by $a$ . $\newline$ $b \cdot a = 8$ $\newline$ $b = \frac{8}{a}$
Solve the inequality: Now let's solve the inequality $7 - 2x \leq 15$ . $\newline$ Subtract $7$ from both sides to isolate the term with $x$ . $\newline$ $7 - 2x - 7 \leq 15 - 7$ $\newline$ $-2x \leq 8$
Divide by $-2$ : Next, divide both sides by $-2$ to solve for $x$ . $\newline$ Remember that dividing by a negative number reverses the inequality sign. $\newline$ $-2x / -2 \geq 8 / -2$ $\newline$ $x \geq -4$
