This questions can be answered with a calculator, but I have an impression it is meant to be a mental calculation problem, which can be solved as follows.

We know that 10*10=100, in otherwords, √ 100 = 10 which is greater than 9.4247.

We also know that √ 108  is greater than √ 100 =10

So we can conclude that
√ 108 > √ 100 = 10  > 9.4247
or simply

√ 108 > 9.4247

by the transitive property of logical propositions.

Solve for x X - 1/2 (8 - x) = x + 3(4 - x) - x<br> A) -32/9<br> B) -9/32<br> C) 32/9<br> D) 9/32
Greeley [361]

Option C

x = \frac{32}{9}

<em><u>Solution:</u></em>

x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x

We have to solve for "x"

From given,

x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x

Solve for brackets

Use distributive property

a(b + c) = ab + ac

Therefore,

x - 4 + \frac{x}{2} = x + 12 - 3x - x

Combine the constants

x + \frac{x}{2} = x - x - 3x + 12 + 4\\\\x + \frac{x}{2} = -3x + 16

Move the variables to left side of equation

x + \frac{x}{2} + 3x = 16

Combine the like terms

2x + x + 6x = 32\\\\9x = 32\\\\x = \frac{32}{9}

Thus option C is correct
