14 students in 21 student got an A on the test so 14/21 people got A. the numerator and the denominator are both divisible by 7 so the simplest form of this fraction would be 2/3
Answer:
(2 - x ) = 1 / 10
Step-by-step explanation:
1 / 5 + 2 / 3 (2 - x ) = 4 / 15
Subtract 1 / 5 from both sides
2 / 3 (2 - x ) = 4 / 15 - 1 / 5
2 / 3 (2 - x ) = 1 / 15
Multiply 3 / 2 on both sides
(2 - x ) = 1 / 15 * 3 / 2
(2 - x ) = 1 / 10
First, multiply 1/2 and 2 by 6 to simplify the equation. Then, subtract 12 from both sides of the equation to get x alone. Finally divide both sides of the equation by 3 to get x on it's own. That is your solution. X=-2/3 I attached a picture of my work. Hope this helped!
Sales tax on the item is ~
Cost of the item is ~
sale tax rate is ~
Therefore, the sales tax rate is 6 %
The very first statement is true. No need to worry about the rest!
Try it out. If you have 9 cups and I have 6... and we both take 3 more... now you have 12 and I have 9. You still have more.
If I have 10 dollars in the bank and you have 5 and we both add -3 to our account by paying a monthly fee - I will have 7 and you will have 2. I have five more than you in both examples.
Adding the same amount to both sides does not change the solution.
