Answer:
The Answer would be 4n
Step-by-step explanation:
Since Marcus ran four times as far this week, we need to know how far he ran last week in order to solve this expression. Since we do not know this information it becomes our variable (n). From the statement we can also infer that there is multiplication since he states the word "times". Therefore our Algebraic Expression would be the following.
P = 4n
P being distance ran by Marcus, and n being distance ran last week by Marcus.

To factor the first problem you have to divide all by 4
The second one is m - <span>√16m +8
To factor the second problem you have to square root it all</span>

F(10)=F(8)+F(9)=21+34=?
5 486 814 rounded to the nearest thousandth so here this is 6th digit:
because 7th digit is 4 we round down:
548.6814≈548,681
Answer: a) 15 b)
Step-by-step explanation:
Let X be the number of days:
a)
For LESSONS:
Jordan does 10 / day ( 10*X)
Marco 5 / day ( 5*X)
Junyi 5 / day ( 5*X)
For TESTS:
Jordan does 5 / day ( 5*X)
Marco 10 / day ( 10*X)
Junyi 8 / day ( 8*X)
for each they need a total of 300
a) 
days for the lessons
b) 
days for the tests
so they need 15 days to finish both tasks
now if Junyi gets sick we just eliminate his contribution
a) 
days for the lessons
b) 
days for the tests
so in 20 days they will finish without him
If jordan works 10 hours a day, we just replace him with 10/24
a) 
days for the lessons
b) 
days for the tests
so at the end to complete both tasks they need 29.58 days
