Answer:
20%
Step-by-step explanation:
To find what percentage is $10 out of $50, we divide 10 by 50:
If we want to get the result in percentage form, we simply multiply it by 100%:
So a tip of $10 on a $50 bill is a tip of 20%.
Answer:
x < 1 and x > -19
Step-by-step explanation:
(4 |x+9|)/5<8
4 |x+9| < 40
|x+9| < 40/4
|x+9| < 10
x + 9 < 10. x < 1. (Positive answer: <)
x + 9 > - 10. x > - 19 (negative answer: >)
Considering the given graph, the profit during the period was of -2 dollars.
<h3>How to add negative numbers along with positive?</h3>
We add all the negative numbers, all the positive numbers, then keep the signal of the higher absolute value, and subtract the values.
From the graph, we have that:
- The sum of the negative numbers is of 8.
- The sum of the positive numbers is of 2 + 4 = 6.
8 > 6, hence the profit is negative given by:
-(8 - 6) = -2 dollars.

To solve this, plug in 1.5 for t in each equation to see which one is true.
1) 2(1.5) = -3 False, 2(1.5) = 3, not -3.
2) 1.5/10 = 15 Falso, 1.5/10 = .15, not 15.
3) 4(1.5) = 6 This is True, so most likely the correct answer, but it's beneficial to check them all.
4) 6(1.5) = 4 False, 6(1.5) = 9, not 4.
Therefore, the correct answer is 4t = 6 because you can plug 1.5 in and it will remain true.
