Question

Solve the equation

1/2x+1/4x=16
what would x be?
a 16
b 21.3
c 32
d 64

Answer 1

b 21.3

Explanation:

Given equation is represented as
`\[(1)/(2)x + (1)/(4)x = 16\]`

Simplifying,

`\[((1)/(2) + (1)/(4))x = 16\]`

`\[=>((2)/(4) + (1)/(4))x = 16\]`

`\[=>(2+1)/(4)x = 16\]`

`\[=>(3)/(4)x = 16\]`

`\[=>x = 16 * (4)/(3)\]`

`\[=>x = (64)/(3)\]`

`\[=>x = 21.3\]`

Hence the value of x is represented by option b.
