nearest tenth:243.9 it goes up because the number after is bigger than 5
nearest hundredth:243.88 it gets rounded up because the number after is 5
(you round up when the number after is 5 or bigger it stays the same when less than 5)
Answer:
$149.27
Step-by-step explanation:
Find the tip first, so:
126.5 · 18/100 = 2277/100 = 22.77
Now that we found the tip, just add that with the bill:
$126.50 + $22.77 = $149.27
What is the system that you have to solve to find the value of x and y?
Answer:
-49/3 and -25/3
Step-by-step explanation:
Let the numbers be represented by f and s (first and second). Then f = s - 8. Also, 2f = 3s + 9. Solve this system for f and s:
Substituting s - 8 for f in the 2nd equation, above, yields
2(s - 8) = 3s + 9, or 2s - 16 = 3s + 9. Then 3s = -25, and s = -25/3. The first number is then f = s - 8, or f = -25/3 - 8, or f = -49/3.
Answer:
B
Step-by-step explanation:
If you plot the line x=1, you would be able to see that it is a vertical line and will pass through (1,9)
