Answer:
4.
Step-by-step explanation:
2+2 equals 4. Plus sign: + you add two on both sides, therefor you get 4 as your answer.
To solve this problem,you need to use the formula d = rd (distance = rates x time)She runs at a speed of 7 mph and walks at a speed of 3 mph. Her distance running is d = 7trwhere tr is the time she spends running Her distance walking isd = 3twwhere tw is the time she spends walking The distances are the same so7tr = 3tw We also know that the total time is 4 hourstr + tw = 4tr = 4-tw Substitute this value of tr in the first equation7tr = 3tw7(4-tw) = 3tw28-7tw = 3tw28 = 10tw2.8 = tw Denise will spend 2.8 hours (2 hours, 48 minutes) walking back and 1.2 hours (1 hour, 12 minutes running.

The first thing we are going to do to find (g°f)(3), is find (g°f)(x). To do that, we are going to evaluate g(x) at f(x):
(g°f)(x)=
Now, we can evaluate (g°f) at 3:
We can conclude that the correct answer is
c. 49
Answer:
$2,400
Step-by-step explanation:
We get 10% of 4,000 by dividing 4,000 by 10.
4,000 ÷ 10 = 400
To get the amount that 4,000 is subtracted by we multiply 400 by 4.
400 × 4 = 1,600
To get the answer we subtract 4,000 by 1,600.
4,000 - 1,600 = 2,400
