Question

Evaluate -a+(-b)−a+(−b)minus, a, plus, left parenthesis, minus, b, right parenthesis where a = 6.05a=6.05a, equals, 6, point, 05 and b = 3.611b=3.611b, equals, 3, point, 611.

Answer 1

−9.661

Explanation:

Let's substitute \blueD{a = 6.05}a=6.05start color #11accd, a, equals, 6, point, 05, end color #11accd and \maroonD{b = 3.611}b=3.611start color #ca337c, b, equals, 3, point, 611, end color #ca337c into the expression.

\begin{aligned} &\phantom{=} -\blueD{a}+(-\maroonD{b}) \\\\ &= -\blueD{6.05}+\left(-\maroonD{3.611}\right) \end{aligned}

​

=−a+(−b)

=−6.05+(−3.611)

​

=−6.05−3.611
