Answer:
Function: 
Amount earned for 10 hours of work: 
Step-by-step explanation:
Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.
Based on the data given in the exercise, you can identify that:
- $140 is a fixed amount.
- For each hour worked on the project, Luigi charges $25. This can be expressed as:

Then, the total amount he charges for a project is the sum of $140 and
. This can be represented with the following function:

To calculate the amount of money earned for 10 hours of work, you must substitute
into the function and evaluate. Then:

Answer:
2x+12=24
first you subtract 12 from both sides
2x+12=24
-12. -12
The 12-12 should cancel itself, the rest of the equation you bring down to get
2x=12 (because 24-12=12)
Now you have 2x=12.
you then divide 2x by both sides.
2x=12
/2x=/2x
The 2x/2x cancels itself out so you then solve for 12/2x.
For this you just divide 12/2 which is 6!
x= 6 is your final answer.
to check this equation you can plug your number back into x to see if it is true! 2(6)+12=24.
6 times 2 is 12 and 12+12 is 24 so your answer (6) is true!
hope this helps! :D
I am going to do number 2 so when you subtract decimals you have to add two zeros like this 10.00 or 0.25 so now when you subtract you get $9.75
M = E/6
a) 185/6 lb = 30.8333... lb
b) 300 lb
If you want some help here, I can tell you!
60% is 60%, since the best way to find out is by converting the two numbers into percents.
You need to find out a decimal first for the second number in order to convert it to a percent. To find a decimal out of a fraction, you put the numerator in the house (I forgot what it was called) and then you put the denominator out. You divide, and you find that 1/3 is actually a repeating decimal, 0.33333333 and so on. You round to 0.34, and that's 34% since 0.34 is 34 out of 100, basically. 34% plus 60% is NOT 100%, and 100% is a whole, so that's why it isn't accurate.
