First, we know that 7 quarts = 1 hour to fill up
So, 48 quarts would take about 6.85 hours to fill up because 48/7=6.85
1 barrel holds 48 quarts which means again, it takes 6.85 hours to fill just one barrel.
25 barrels of 48 quarts are picked up at a time.
25 * 6.85 hours = 171.25 hours in one trip.
There are 24 hours in a day, so take 171.25/24 = 7.13 days.
Answer:
<span>−84</span>
Explanation:
Let x be the unknown number.
From the queston we can form the equation
<span><span>x<span>(−7)</span></span>−2=10</span>
Move <span>−2</span> to the right hand side
<span><span><span>x<span>(−7)</span></span>=10+2</span><span><span>x<span>(−7)</span></span>=12</span></span>
Multiply both sides by <span>−7</span> to get the unkonwn no.
<span><span><span>−7</span>⋅<span>x<span>(−7)</span></span>=12⋅<span>(−7)</span></span><span>
x=−84</span></span>
Hope this helps
