Step-by-step explanation:

10. Take the amount of onion and divide by the number of servings

1/2 ÷ 6

Copy dot flip

1/2 * 1/6

1/12

There is 1/12 of an onion in each serving

12. 1/2 * 3/4 = 3/8

The first is 3/4 of 1/2 The second is 1/2 of 3/4

They are equal

Question #10:

To find what fraction of an onion is used per serving, divide the total amount of onion by the total number servings.

1/2 ÷ 6 = 1/12

Therefore, 1/12 of an onion was used per serving.

Question #12:

1/2 of 3/4 means that we multiply 1/2 to 3/4.

3/4 * 1/2 → 3/8

3/4 of 1/2 means we multiply 3/4 to 1/2.

1/2 * 3/4 → 3/8

Therefore, both expressions are similar.

Best of Luck!

If 7x is an odd integer, represent the next odd integer as an algebraic expression in x.

blagie [28]

Given :

7x is an odd integer.

To Find :

The next odd integer as an algebraic expression in x.

Solution :

All positive integers are :

1 , 2 , 3 , 4 , 5 , ......

From the above series we noticed that every other odd number is 2 more than the previous one.

So , 7x is an odd number.

Therefore, next odd number is 7x + 2.

Hence, this is the required solution.

You can win concert tickets from a radio station if you are the first person to call when the song of the day is played, or if y

Anit [1.1K]

The song of the day is announced at a random time between 7:00 and 7:30, so you have a 30-minutes span of time where the song could be announced. If you start listening to the radio 20 minutes in, you're at 2/3 of the time. So, there is a 2/3 chance that the song has already been chosen, and a 1/3 chance that it will be announced in the remaining 10 minutes.

Similarly, the trivia question is asked at a random time between 7:15 and 7:45 so there is again a 30-minutes span of time. But this time, we're only 5 minutes late, so there is a 5/30=1/6 chance that the question was already asked, and a 25/30=5/6 chance that the question will be asked in the remaining 25 minutes.

So, there are four scenarios:

You have missed both the song of the day and the trivia question. Given all we said, this event has a chance of

$\dfrac{2}{3}\cdot\dfrac{1}{6} =\dfrac{2}{18}$

You miss the song, but not the trivia:

$\dfrac{2}{3}\cdot\dfrac{5}{6} =\dfrac{10}{18}$

You miss the trivia, but not the song

$\dfrac{1}{3}\cdot\dfrac{1}{6} =\dfrac{1}{18}$

You don't miss anything:

$\dfrac{1}{3}\cdot\dfrac{5}{6} =\dfrac{5}{18}$

You're interested in the probability of missing either of the announcements, so you want to sum the two middle cases (in the first you miss everything, in the second you don't miss anything).

Your result is thus

$\dfrac{10}{18}+\dfrac{1}{18} = \dfrac{11}{18}$

Expand & simplify 2 ( b + 4 ) + 5 ( b − 3 )

Usimov [2.4K]

Answer:

7b - 7

Step-by-step explanation:

You can use distributive property which is x (a + b) = x*a + x*b and x (a - b) = x*a - x*b. Therefore, the expression is 2*b + 2*4 + 5*b - 5*3 which is:

2b + 8 + 5b - 15, which is, if you combine like terms:

7b - 7
