Since this line is one single line you want to add the two parts rather than multiply.

(x - 7) + (x - 3) = 12

x - 7 + x - 3 = 12

Next you want to simplify everything so add the values with the variables together and add the constants together

2x - 10 = 12

Get the term with the variable on one side

2x = 22

Divide by 2 on both sides to find x

x = 11

Readme [11.4K]

Answer:

25,625

Step-by-step explanation:

If your current salary is the 100%, and you get a 2.5% increase, that means the new salary would be 102.5% of 25,000. This percentage could also be written as 1.025, which you would multiply to 25,000 to get your new salary.

1.025 · 25,000 = 25,625

Therefore, your new salary would be $25,625

Dr. Hilton uses the graph to determine if a patient has a
seropon [69]

Answer:

At least 100 degrees

Step-by-step explanation:

Here, we want to make an inequality assertion from the graph drawn by Dr Hilton.

The correct conclusion here is that a person has a fever once his/her temperature is greater than or equal to 100 degrees.

How do we know this from the graph? from the graph, we can see a yellow circular mark placed on 100. This indicates that we are starting our consideration from the point 100 degrees. What we don not know is if our answer is less than, greater than, less than or equal to or greater than or equal to.

The correct answer is however greater than or equal to. Firstly we check the fill of the yellow circular mark. Once it is filled and not left blank, then it indicates an equal to relationship, meaning 100 degrees itself is included in the range.

finally we then consider the direction it faces and from here we can conclude that it is greater than or equal to
