Step-by-step explanation:

Calculate C by adding corresponding components of A + B

C = $\left[\begin{array}{ccc}4\\-7.5\\\end{array}\right]$ + $\left[\begin{array}{ccc}-2.5\\5\\\end{array}\right]$

= $\left[\begin{array}{ccc}4-2.5\\-7.5+5\\\end{array}\right]$

= $\left[\begin{array}{ccc}1.5\\-2.5\\\end{array}\right]$

-5x - 49 > 113
Add 49 to both sides
-5x > 162
Divide both sides by -5
x > -32.4
Hope this helps!
