(3x-4)/(14)=(9)/(10) Solve the proportion. Round to the tenths

____ [38]

The value of "x" is 5.5

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

Given that we have to solve the proportion

$\frac{3x - 4}{14} = \frac{9}{10}$

We can solve the above given proportion for "x" by cross multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable "x"

$\rightarrow \frac{3x - 4}{14} = \frac{9}{10}\\\\\rightarrow 10(3x - 4) = 14 \times 9\\\\\rightarrow 30x - 40 = 126\\\\\rightarrow 30x = 126 + 40\\\\\rightarrow 30x = 166\\\\\rightarrow x = 5.533$

On rounding to nearest tenth we get 5.5

Thus value of "x" is 5.5
