Ali was asked to simplify the expression 3(x - 6) + (4x + 12) - 6x. His work is shown below.


3(x - 6) + (4x + 12) - 6x

3x - 9 + 4x + 12 - 6x

(3x + 4x - 6x) + (-9 + 12)

x + 3

Answers

Answer 1

Answer:

Step 2 is wrong.

It should be 3x – 18 + 4x + 12 – 6x

Explanation:

3(x – 6) + (4x + 12) – 6x →

3x – 18 + 4x + 12 – 6x →

(3x + 4x – 6x) + (-18 + 12) →

x – 6

The graph of the system of linear inequalities is shown in the picture with points.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The system of linear inequalities:

y < −x + 3

y ≥ 2x − 1

After plotting the graph, the graph will be a linear equation(as shown in the picture)

From the graph:

The two points are (-2, 2) and (-1, 1)

The above two points satisfy the system of linear inequalities.

The two points that are not solutions:

(4, 2) and (5, 2)

Thus, the graph of the system of linear inequalities is shown in the picture with points.

Six cousins inherited a total of 5/8 of their great aunt’s assets, which they divided evenly. What fraction of their great aunt’s assets did each cousin inherit?

Answers

Answer:  5/48

============================================

Work Shown:

We'll divide the total 5/8 evenly among the 6 cousins.

(5/8) ÷ 6 = (5/8) ÷ (6/1)

(5/8) ÷ 6 = (5/8) * (1/6)

(5/8) ÷ 6 = (5*1)/(8*6)

(5/8) ÷ 6 = 5/48

Each cousin gets 5/48 of the aunt's assets.

So for instance, if the aunt had $48,000 in assets, then each cousin gets (5/48)*(48,000) = 5000 dollars.

------------------

An alternative approach:

Draw 6 rectangles side by side that represent the 6 cousins. Then divide each rectangle into 8 pieces, with 5 pieces shaded. The yellow pieces represent the amount given to the cousins. For any given rectangle, 5/8 of it is shaded yellow. Refer to the diagram below.

Overall we have 6*8 = 48 pieces.

The first cousin gets 5 yellow pieces out of 48 total. The same applies to the other five cousins. So this is a visual way to arrive at the answer 5/48.

B. The school prom committee sold presale tickets for
$18 each. Couples that showed up on the day of the
dance has to pay $24 each. There were 334 tickets
that were sold and the committee made $7320. How
many students purchased tickets at the dance?

Answers

Answer:

218 students purchased tickets at the dance.

Step-by-step explanation:

Let,

x be the number of presale tickets

y be the number of tickets sold at the dance

According to given statement;

x+y=334      Eqn 1

18x+24y=7320    Eqn 2

Multiplying Eqn 1 by 18

18(x+y=334)

18x+18y=6012      Eqn 3

Subtracting Eqn 3 from Eqn 2

(18x+24y)-(18x+18y)=7320-6012

18x+24y-18x-18y=1308

6y=1308

[tex]\frac{6y}{6}=\frac{1308}{6}\\y=218[/tex]

Therefore,

218 students purchased tickets at the dance.

basket contains 7 green apples, 9 red apples, 10 nectarines, and 10 oranges. Sandy randomly chooses a piece of fruit, eats it, then selects another. Find the probability of selecting a red apple then a oranges?

Answers

Answer:

So the probability is 1/14 or 7.14%

Step-by-step explanation:

First lets  calculate the total number of fruits:

[tex]7+9+10+10=36[/tex]

Now, calculating the probability of the first fruit being a red apple, we have 9 red apples among 36 fruits, so the probability is 9/36.

Then the probability of the second fruit being an orange will be 10/35 , since we will have 10 oranges among 35 fruits.

Finally the final probability is the product of these two probabilities , so we have:

[tex]P=\frac{9}{36} .\frac{10}{35} =\frac{1}{4} .\frac{2}{7} =\frac{1}{14}[/tex]

So the probability is 1/14 or 7.14%

Wendy has a​ $30 to spend at the store. She wants to buy 5 pairs of socks for​ $1.99 each and a scarf for​ $20.49, including tax. She uses rounding to estimate the​ cost: . Wendy says she has enough money to cover the price of everything. Is she​ correct? Explain.

Answers

Answer:

Wendy does not have enough of money to cover the price of everything

Step-by-step explanation:

If Wendy has $30 and wants to but 5 pairs of socks that cost $1.99($2.00) each and a scarf for $20.49, she wouldn't have enough of money because the 5 pairs of socks would be $10 and if you subtract that from $30, she would only have $20 dollars left, so she wouldn't have enough money to pay for the socks and scarf, which also means she would only have to pick one of the two items she wants, either she pays for the socks, or she pays for the scarf, but she can't pay for both.
