<span>The word problem gives a rate of oil consumption at a rate of 25 gallons per 3 hours and 45 minutes. 3 hours and 45 minutes can be displayed as 3.75 hours. so you can say the generator consumes oil at a rate of 25 gallons per 3.75 hours. The following equation give you the oil consumption on a per hour basis; 25/3.75 and that gives you 6.67 gallons per hour. In 6 hours the generator will consume 40 gallons.</span>
Answer:
$17.50
Step-by-step explanation:
$18.37=x+5%
18.37=1.05x
18.37/1.05=x
x=$17.50
<h3>
12 = -5x/4 - 8</h3>
Multiply both sides of the equation by 4.
<h3>48 = −5x − 32</h3>
Swap the sides so that all variable terms are on the left side.
<h3>−5x − 32 = 48</h3>
<em>Add 32 to both sides.</em>
<h3>−5x = 48 + 32</h3>
<em>Add 48 and 32 to get 80.</em>
<h3>−5x = 80</h3>
<em>Divide both sides by −5.</em>
<h3>x = 80/-5</h3>
<em>Divide 80 by −5 to get −16.</em>
<h3>x= −16</h3>
