Answer:
<h2>2.) When dividing by −2, he did not change the direction of the sign. </h2>
Step-by-step explanation:
-4(x + 8) ≤ -2x + 50 <em>use the distributive property: a(b + c) = ab + ac</em>
-4x - 32 ≤ -2x + 50 <em>add 2x to both sides</em>
-4x + 2x - 32 ≤ -2x + 2x + 50
-2x - 32 ≤ 50 <em>add 32 to both sides</em>
-2x - 32 + 32 ≤ +50 + 32
-2x ≤ 82 <em>divide both sides by (-2) / </em><em>flip the inequality sign</em><em>/</em>
x ≥ -41

Answer:
-3
Step-by-step explanation:
The equation could be written with decimals to make it easier:
0.5 + (-3.5) = ?
I am going to make an example
You owe your friend $3.50
That can be represented as this:
$-3.50
You pay your friend $0.50
Now you only owe your friend $3.00
Hope this helped :)
