Answer:
18 times the first equation and 8 times the second equation
Step-by-step explanation:
we have
------> first equation
------> second equation
step 1
Multiply the second equation by 8 both sides to remove the fraction in the variable y
step 2
Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y
step 3
Adds the new equation 1 and equation 2
The y-term is eliminated
therefore
The answer is
18 times the first equation and 8 times the second equation
1/5 would be the correct one.
Answer:
It would be 6 dollars
Step-by-step explanation:
20 percent of 30 dollars is 6 dollars.
If an item costs 30 dollars and it's on sale for 20 percent off, how much will you save? To figure this out, you need to find 20 percent of 30.
This is easy to do in your head. Think of what 10 percent would be. 10 percent of 30 would be the same as .10 x 30, or 3. So, 10 percent off is 3 dollars off.
20 percent is twice as much as 10 percent. If 10 percent off is 3 dollars, then 20 percent off would be 2 x 3 or 6.
20 percent of 30 dollars would be 6 dollars.
This is actually good, because it helps improvement more. They may do a ¨good¨ landing, but there could still be flaws. Due to my own experiences in reacting to criticism and praise, praise will make you calm down, and think you are perfect, making you more lazy the second time you do it, thinking it will all be okay. Criticism toughens you up, and helps you do better everytime you do what you do.
