The correct way to write this equation is .25x-3=12. The .25 is interchangeable with
The right answer is the constant of proportionality
If two variables are related and this relationship is that there is a<em> constant ratio</em> between them, then we are talking about proportionality. There are two types of proportionality.
1) Direct Proportionality:
In a mathematical language this is given by this equation:

where
is in fact this constant of proportionality. If
<em>increases,</em>
also <em>increases</em> at the same rate. On the other hand, If
<em> decreases, </em>
also <em>decreases</em> at the same rate.
2) Inverse Proportionality:
In a mathematical language this is given by this equation:

where
is also called the constant of proportionality. If
<em>increases,</em>
<em>decreases</em> at the same rate. On the other hand, If
<em>decreases,</em>
<em>increases</em> at the same rate.
Answer:
The car's average 18 number of miles per gallon
Step-by-step explanation:
The car has different efficiencies depending if its used on highway or city streets.
The efficiency on a highway is:

The efficiency for city driving is:

We now that the car uses twice as many gallons for city driving as for highway driving. This means that, for every gallon consumed, 2/3 are for city driving and 1/3 are for highway driving.
Then, we can calculate how many miles makes the car on average as:

Answer:
Write seven and twelve hundredths in standard form.

The Alternate Interior Angles theorem states, if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent. A theorem is a proven statement or an accepted idea that has been shown to be true.
