Hey there! Thanks for asking your question here on Brainly!

First, we'll need to get common denominators in each of the two fractions. This can be done by multiplying 1/2 by 5/5 and 1/5 by 1/2.


1/2 x 5/5 = 5/10

1/5 x 1/2 = 1/10


Next, since we now have common denominators, we can simply add the numerators of the fractions together. When adding or subtracting fractions, we have to get common denominators, then add the numerators together. In the final answer, the denominators will remain the same and will not be added together as we would do with the numerators.


5/10 + 1/10 = 6/10


Lastly, we'll need to simplify the fraction. Both the numerator and denominator can be divided by two.


(6/10) / 2 = 3/5


Our final answer is 3/5!


Hope this helps!! :)

Steven has some money. If he spends $9.00, then he will have 3/5 of the amount he started with​
ELEN [110]

Answer:

m - 9 = 3/5 m (Steve has some money. After spending $9, he now has 3/5 of his original amount)

So it's just the matter of isolating m. Subtract m from both sides:

-9 = -2/5 m

Now you just need to multiply both sides by -5/2 to get your final answer.

2. In how many ways can you form 3-letter "words" from the letters of "Adelphi" so that the first and last letters are vowels? N
kondaur [170]

Answer:

The total number of ways are 30.

Step-by-step explanation:

Consider the provided information.

We need to write 3-letter "words" from the letters of "Adelphi" so that the first and last letters are vowels.

The number of letters in "Adelphi" = 7

The number of vowels are = 3

It is given that the first and last letters are vowels.

For first letter we have 3 choices, and for the last letter we have 2 choices as repetition is not allowed.

If we have selected first and last letter that means now we have 5 letters for the middle letter. (7-2=5)

So the number of possible choices for the 2nd letter is 5.

Hence, the total number of ways are: 3×5×2 = 30 ways

1) The bakers at Healthy Bakery can make 290 bagels in 10 hours. How many
Ivenika [448]

Answer:

667 bagels in 23 hours

29 bagels per hour

Step-by-step explanation:

We first find the unit rate in bagels per hour.

(290 bagels) / (10 hours) = 29 bagels/hour

Now we find the number of bagels made in 23 hours.

23 hours * 29 bagels/hour = 667 bagels

It takes me 12 minutes to run 2 kilometers. How long will it take me to run 10,000 meters?
galina1969 [7]
60min or 1 hour

Because 2km is equal to 2000m
Therefore you multiply 12 min by 5 (because 2000m x 5 is 10000m)
