What is the first step to solve the absolute value equation 2|x+5|=16 for x?????
1 answer:
Divide both sides by 2.
<span><span><span><span><span>2<span>(<span>|<span>x+5</span>|</span>)</span></span>2</span></span></span>=<span><span><span>162
</span></span></span></span><span><span>|<span>x+5</span>|</span>=8
</span>Solve Absolute Value.
<span><span>|<span>x+5</span>|</span>=8
</span>We know either<span><span>x+5</span>=8</span> or <span><span>x+5</span>=<span>−8
</span></span><span><span>x+5</span>=8 </span>
<span><span><span>x+5</span>−5</span>=<span>8−5</span></span>(Subtract 5 from both sides)
<span>x=3</span><span><span>

snack initial total
fee fee $ spent
Answer:
69
Step-by-step explanation:
All the given arcs cover the entire circle circumference, so their measures add up to a full 360.

4x + 84 = 360
4x = 276
x = 69
