The solution 349 is given, and its number 3, 4 and 9 determine how many times 13 can be subtracted:
The first subtraction is 3x13 (x100) = 3900
The second subtraction is 4x13 (x10) = 520
The third subtraction is 6x13 = 78
So the answer is 520, which is also what you get when you subtract 78 from 598 of course.
Put in slope intercept form so the first equation would be y=-x-9 then the second one will be y=-5/2x-16
Answer:
Trevor read 157.5 pages this week.
Step-by-step explanation:
Simple multiplication.
Multiply 5 by 5 first to get 25, carry the 2 on top and then multiply 3 by 5 to get 15, make sure to add 2 to get 17. The first line should be 175.
Put a 0 on the last digit to solve for the next digit. Multiply 4 by 5 to get 20, carry the 2 on top and then multiply 3 by 4 to get 12, make sure to add 2 to get 14. The second line should be 1400.
Add the numbers up to get 1575, since there is one number behind the decimal, you should put a decimal in front of the last 5 for the answer in which it is 157.5.
Answer:
1) Ben, 2) 
, 3) 
, 4) 
Step-by-step explanation:
1) Ben has a higher rate of memorization, since the coefficient of the second power is lesser than the one from Alice.
2) The number of words can be estimated by integrating the function:
Alice
Ben
3) The average amount of words per minute is:
4) The average amount of words per minute is:
Answer:
After 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.
Step-by-step explanation:
We are given the following in the question:
Total area of lawn = 5,625 square feet
Rate of mowing lawn = 75 square feet each minute
Area of lawn mowed in 5 minutes =
Square feet does Kaitlyn still have to mow after 5 minutes
Thus, after 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.
