73.
18 = 3x
(divide both sides by 3 )
6 = x
( multiply both sides by
)
6
= 3x [
×
= 3 ]
divide both sides by 3
x = 2
74.
24 = 2x
( divide both sides by 2 )
12 = x
( multiply both sides by
)
12
= 2x ( divide both sides by 2 )
x = 6
75.
9
× x = 18
( divide both sides by 9
)
x = 2
76.
2 = x ×
( multiply both sides by
)
2
= 4x ( divide both sides by 4 )
x =

Answer: 187.5 cups of sauce in total
Step-by-step explanation: easy multiply 27 by 7.5
We want to know when we brought it back in to the room. at that time
the temperature difference is 80 - 42 = 38 so we have to solve
<span>
38=9<span>e<span>^−.3344t</span></span></span> for t
this time we get
<span><span>38 / 9</span>=<span>e^<span>−.3344t</span></span></span>
<span>t=<span><span>ln(<span>38 / 9</span>)</span><span> / −.3344</span></span></span>
<span>t=−4.3</span>
so 4.3 minutes before 2:10
