Answer:

b 21.3

Step-by-step explanation:

Given equation is represented as [tex]\[\frac{1}{2}x + \frac{1}{4}x = 16\][/tex]

Simplifying,

[tex]\[(\frac{1}{2} + \frac{1}{4})x = 16\][/tex]

[tex]\[=>(\frac{2}{4} + \frac{1}{4})x = 16\][/tex]

[tex]\[=>\frac{2+1}{4}x = 16\][/tex]

[tex]\[=>\frac{3}{4}x = 16\][/tex]

[tex]\[=>x = 16 * \frac{4}{3}\][/tex]

[tex]\[=>x = \frac{64}{3}\][/tex]

[tex]\[=>x = 21.3\][/tex]

Hence the value of x is represented by option b.
