Answer:
x = 7/2 = 3 1/2
Step-by-step explanation:
2x + 5= 12
Subtract 5 from each side
2x + 5-5= 12-5
2x = 7
Divide each side by 2
2x/2 =7/2
x = 7/2
Changing from an improper fraction to a mixed number
2 goes into 7 3 times with 1 left over
x = 3 1/2

The right answer is: <em>The binomial expression 2w + 6 represents the length of the fish tank.</em>
Dylan has a fish tank, so we assume that this tank is a cube. In this way, the volume of the tank is given by this expression:

Where:
h: height
w: width
l: length
We know the following things:
FIRST.<em> He knows its height, h, is one inch less than twice the width, w.</em>
This can be expressed as the following equation:

SECOND. <em>The length, l, of the fish tank is seven inches longer than the height.</em>
We can express this statement as follows:

By substituting
in
