evaluate ( x - y ) if ( x = - 5 \frac { 1 } { 4 } ) and ( y = - 6.8 ). write your answer as a decimal to the nearest hundredth.
Answer
Explanation:
Step1: Substitute the values of (x) and (y)
Given (x = - 5\frac{1}{4}=-5.25) and (y=-6.8), substitute into (x - y). So, (x - y=-5.25-(-6.8))
Step2: Simplify the expression
Using the rule (a-(-b)=a + b), we have (-5.25-(-6.8)=-5.25 + 6.8) (-5.25+6.8 = 1.55)
Answer:
(1.55)
