Q32. - Algebra 1

Question

Evaluate each expression if $\mathit{a}\mathbf{=}\mathbf{-}\mathbf{1}\mathbf{,}\mathit{b}\mathbf{=}\mathbf{4}\mathbf{,}\mathbf{\text{\hspace{0.33em}and }}\mathit{c}\mathbf{=}\mathbf{6}$.

32.$\mathbf{-}\mathbf{10}\mathit{c}\mathbf{+}\mathbf{3}\mathit{a}\mathbf{+}\mathit{a}$ 

Step-by-Step Solution

Answer

The value of the expression is $\mathbf{-}\mathbf{64}$.

Step 1 – Write the given information

The expression given is

$-10c+3a+a$

And

$a=-1,b=4\text{ and }c=6$

Step 2 - DESCRIPTION OF STEP

To solve the given expression substitute variables a,  and c by $-1$, and 6 respectively, as:

$\begin{array}{c}-10c+3a+a=-10\left(6\right)+3\left(-1\right)+\left(-1\right)\\ =-60-3-1\\ =-64\end{array}$

Thus, $-10c+3a+a=-64$.
