What are the integer solutions to the inequality below? 3 < 3 x − 1 < 2 x + 6

natita [175]

Answer:

4/3<x<7

Step-by-step explanation:

Given the inequalities

3 < 3 x − 1 < 2 x + 6

Add 1 to all sides

3+1 < 3x-1+1<2x+6+1

4 < 3x < 2x + 7

Split

4 < 3x

3x > 4

x > 4/3

4/3 <x

Also

3x < 2x + 7

3x-2x < 7

x <7

Combine

4/3<x<7

Hence the required solution is 4/3<x<7

Answer:

$\frac{7\sqrt{5} }{8}$

Step-by-step explanation:

Using the rules of radicals

$\sqrt{\frac{a}{b} }$ = $\frac{\sqrt{a} }{\sqrt{b} }$

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Given

$\sqrt{\frac{245}{64} }$ = $\frac{\sqrt{245} }{\sqrt{64} }$

Simplifying the radicals

$\sqrt{245}$

= $\sqrt{5(7)(7)}$

= $\sqrt{49(5)}$

= $\sqrt{49}$ × $\sqrt{5}$ = 7 $\sqrt{5}$

and

$\sqrt{64}$ = 8

The simplified radical is

$\frac{7\sqrt{5} }{8}$
