Answer:
number 2 and 4
Step-by-step explanation:
30% is equivalent to 3/10
So any fraction that can be simplified to 3/10.
Another way to to think about it if you multiply 3/10 by any number over it self because that is equivalent to 1.
Like 3/10 * 2/2 =6/20 is also equal to 30%
Answer:
Step-by-step explanation:
Let 
be the number of bags with 8 onions and let 
be the number of bags with 3 onions. We have the following system of equations:
Subtracting from both sides of the first equation, we get 
. Substitute this into the second equation:
Therefore, the number of 8-onion bags is:
Thus, the chef got 4 8-onion bags and 3 3-onion bags.
<h2>
Hello!</h2>
The answer is:
The slope of the hill is equal to 2.
<h2>Why?</h2>
To solve the problem, we need to remember that the slope of a line, is the rate of increase or decrease of the line.
From the statement we know that the tallest peak of the roller coaster is 310 feet (y), while the roller coaster travels 155 horizontal feet (x), so, calculating we have:
Then, substituting the given information and calculating, we have:
We have that the slope of the hill is equal to 2.
Have a nice day!
Answer:
6b is a simpler expression that is equivalent to 4b+2b.
Step-by-step explanation:
Given : At a library book sale, hardcover books sell for $4 and paperbacks sell for $2.
The expression 4b+2b represents the total cost for b hardcover books and b paperbacks.
We have to write a simpler expression that is equivalent to 4b+2b.
Equivalent expression are expression which are different in seeing but when we solve both we get the values same as the original expression.
Given expression is 4b+2b,
We can take 2b common from terms to get an equivalent expression as,
4b+2b = 2b(2+1) = 2b(3) = 6b.
Thus, 6b is a simpler expression that is equivalent to 4b+2b.
