Q81. - Algebra 2

Question

Evaluate each expression if $a=3$, $b=-2$, and $c=1.2$.

$a-\left[b\left(a-c\right)\right]$

Step-by-Step Solution

Answer

The required answer is $6.6$.

Step 1- Perform the substitution

Substitute the provided values of a, b and c into the provided expression.

$3-\left[-2\left(3-1.2\right)\right]$

Step 2 – Simplify the expression

Write the obtained expression in the simplified form.

$\begin{array}{c}3-\left[-2\left(1.8\right)\right]=3-\left(-3.6\right)\\ =3+3.6\\ =6.6\end{array}$

Step 3- Make the conclusion

As nothing can be done further with the expression so obtained expression is the required expression.
