<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>
Let n be the unknown value
n + (n+2) + (n+4) = 408
Then we would simplify by combining like terms
n + n + 2 + n + 4 = 408
3n+6=408
-6 -6
--------------
3n=402
Divide.
3n=402

3 3
n = 134.
So the first integer is 134. Then plug in the rest to the n+2 and n+4
134+2= 136
134+4= 138
The integers are then 134, 136, 138
Answer: 10.50 dollars
Step-by-step explanation:
3.50 x 3 = 10.50
Jacob used 1/7 of a liter
of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to
mixed fraction
=> x = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.
