The answer is A, because if he took the % of how many people attended the last game, that wouldn't be a sample. If he took a sample of the friends of the players, they don't necessarily have to be a part of the town. If he took a sample of the people who are on sports teams, that would just be dumb. He wanted to know how many people from the TOWN would attend. SO if he took a random sample of the people from the TOWN, he would have the most accurate answer.

9/11 - 1/2 in it's simplest form

Murrr4er [49]

Answer:

7/22

Step-by-step explanation:

Step 1: Define/explain.

To subtract fractions with different denominators, you must first find the least common denominator (LCM).

You can do this by listing the multiples of each denominator.

Step 2: Solve.

11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110

2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22

22 is the LCM.

Now, we change the fractions to where they both have denominators of 22.

**REMEMBER: WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MULTIPLY IT BY THE NUMERATOR AS WELL!!**

$9/11*2/2=18/22$

$1/2*11/11=11/22$

Now, subtract as normal.

$18/22-11/22=7/22$

$7/22 (simplified).$

Step 3: Conclude.

Therefore, 9/11 - 1/2 = 7/22.

Help me please!! Joe went to a fast food restaurant and bought 4 orders of fries and 2 burgers for $14. Becca went to the same f

pashok25 [27]

Here are the equations that are represented by the scenarios:

4x + 2y = $14 (Joe)
3x + y = $9 (Becca) or y = 9 - 3x

To find the cost of each burger and fry you will solve the second equation for y and substitute it in for the y in the first equation. This will put everything in terms of x, the price of a fry.

4x + 2(9 - 3x) = $14
4x + 18 - 6x = 14
-2x +18 = 14
-18 -18
-2x = -4
-2 -2
x = 2

Fry cost $2, and burgers cost (9 - 3 x 2) or $3.
