Step-by-step explanation:
-3.2 = -32/10 = -16/5 . . . . matches choice D
_____
<em>More detail</em>
Any finite decimal can be converted to a fraction by considering the place value of the digits.
3.2 = 3×1 + 2×(1/10)
= 3 + 2/10 = (30 +2)/10 = 32/10
Then common factors can be cancelled from numerator and denominator.
32/10 = (2·16)/(2·5) = 16/5
The negative sign can be applied as required.
-3.2 = -(3.2) = -(16/5) = -16/5
An equation is formed of two equal expressions. The correct option is C.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The ordered pair that is a solution to the system of linear equations can be found as shown below,
6x + 5y = -7
Solving for y,
y = (-7-6x)/5
In the second equation substitute the value of y,
2x - 4y = -8
2x - 4[(-7-6x)/5] = -8
2x + (28/5) + (24x/5) = -8
10x + 28 + 24x = -40
34x = -68
x = -2
Since the only option in which the value of x is -2 is option C. It is the correct option.
Hence, the correct option is C.
