Morten Andersen played in NFL for 25 years write and solve an equation to find how many points he averaged each year
soldi70 [24.7K]

Answer:

r =\frac{2437points}{25 years} =97.45 \frac{points}{year}

So then we have that Morten Andersen scored on average 97.45 points per year in his career.

Step-by-step explanation:

Assuming the following table on the figure attached.

We see that the career points for Morten Andersen was 2437. That include all the points over alll the years the he played in the NFL.

Since the total years played by Morten Andersen was 25 we can write the following equation:

25 r =2437

Where r represent the rate of points average per year.

If we solve for r from the last equation we can divide both sides of the equation and we got:

r =\frac{2437points}{25 years} =97.45 \frac{points}{year}

So then we have that Morten Andersen scored on average 97.45 points per year in his career.

translate this verbal expression to a algebraic expression eight more than six times a number added to one more than nine times
34kurt
I will right it sideways. you can use this strategy later on if you would like. I put (parentheses) around what is optional to include. the = to the left of the second word number is to show that the number is equal. if there are two different variables you would put a crossed out equal sign.
_______________
eight= 8 l
more than= +
six= 6
times= x
(a)number= n l
_______________
added (to)= +
_______________
one= 1 l
more than= +
= number= n l
_______________

(I tried to do parentheses)

then, you rewrite what you wrote beside the words!

(8+6n)+(1+n)

that is your equation!
