Answer:
<u>0.125 miles per gallon.</u>
Step-by-step explanation:
After 200 gallons used the freight train has traveled 25 miles. This means that we need to divide both sides by 200 to get a singular gallon's worth of miles traveled. 200/200 is 1, and 25/200 is 0.125.

<u><em>IF</em></u> it were how many gallons per mile, you would divide both answers by 25 resulting in <u>8 gallons per mile.</u>
Answer: If element Q has 11 protons, its atomic <u>number</u> is 11.
Step-by-step explanation:
The atomic number of a chemical element is the total number of protons that each atom of that element has.
In other words: it indicates the amount of protons that is present in the nucleus of an atom.
In this sense, the periodic table of the elements arranges the chemical elements in the form of a table, ordered by their atomic number (number of protons), by their configuration of electrons and their chemical properties.
The coordinates of the midpoint of the segment joining the two points (0, 2) and (6, 4) is (3, 3)
<h3><u>Solution:</u></h3>
Given that two points are (0, 2) and (6, 4)
To find: coordinates of the midpoint of the segment joining the two points
<em><u>The midpoint of line joining two points is given as:</u></em>
For a line containing two points 
and 
In the given sum, two points are (0, 2) and (6, 4)
Substituting the values in given formula,
Thus the required midpoint is (3, 3)
Answer:
x= -0.5
Step-by-step explanation:
5(2x+4)=15
