Which is a correct expansion of the following expression?

18(x – 3) – 26


A. 18x – 80

B. 18x + 80

C. 18x + 28

D. – 62x

Answers

Answer:

A. 18x – 80

Step-by-step explanation:

18(x - 3) - 26

18x - 54 - 26

18x – 80

The answer is a. 18x - 80

Because first you will expand the brackets, for this you will multiply everything that is outside the bracket to what’s inside (18 times x) which will give you 18x and (18 times -3) which will give you -54

Now your equation will be

18x -54 - 26

Next you will workout the liked terms with are -54 and -26, since they are both negative just add them together and keep the sign.

To get your final answer

18x -80

If we already know that XY=WZ, which additional fact would prove that quadrilateral WXYZ is a parallelogram?

Answers

Answer:

WX=ZY would prove that the quadrilateral WXYZ is a parallelogram

Step-by-step explanation:

The additional fact that would prove that quadrilateral WXYZ is a parallelogram is '' XY = YZ''.

If we already know that XY=WZ,

What is parallelogram?

A Parallelogram is a four-sided quadrilateral whose opposite sides are parallel and congruent to each other.

The opposite angles of a parallelogram are equal.

These bisectors intersect each other at 90 degrees.

And it means that they are perpendicular.

Since they are perpendicular, we find that there 4 congruent triangles, XY is parallel to WZ, and WX is parallel to YZ.

Additionally, opposite angles are equal.

These two latter findings are the characteristics of the parallelogram.  

Hence, the additional fact that would prove that quadrilateral WXYZ is a parallelogram is '' XY = YZ''.

Sally's job pays her $30 per hour.
If Sally works 6 hours, how much money would she earn?
I

Answers

180 $
I hope that helps

Answer:

$180

Step-by-step explanation:

If Sally's job is paying her $30 PER HOUR, and we know that she works 6 hours, you would need to find how to put those two numbers together to get how much total money she earns. Since she gets 30 dollars per hour, and she works 6 hours, this hints to us that it is a multiplication problem. So, we would do 30×6= 180.

Larissa plans to bake at most 10 loaves of bread. She makes x loaves of banana bread that sell for $1.25 each and y loaves of nut bread that sell for $1.50 each. She hopes to make at least $24 in sales. Write and graph a system of inequalities for this situation. What does the graph show?

Answers

Answer:

1) The system of inequalities are;

x × 1.25 + y × 1.5 ≥ 24

x + y ≤ 10

Please find attached the required graph of the two inequalities ,created with Microsoft Excel

2) The graph of inequality shows that Larissa cannot to make less than 10 loafs of bread and sell them for over $24 at the given prices of each loaf of bread

Step-by-step explanation:

1) The maximum number of loaves Larissa plans to make = 10

The price at which she sells each of x loaves of banana bread = $1.25

The price at which she sells each of y loaves of nut bread = $1.50

The total amount she hopes to make = $24

The system of inequalities are;

x × 1.25 + y × 1.5 ≥ 24

x + y ≤ 10

Making y the subject of both inequalities gives;

For the first inequality, we have,

y ≥ 24/1.5 - 1.25/1.5·x which gives;

y ≥ 16 - 5/6·x

For the second inequality, we have,

y ≤ 10 - x

Please find attached the required graph of the two inequalities

2) From the attached graph of inequality, created with Microsoft Excel, it shows that it is not possible for Larissa to make less than 10 loafs of bread and at the same time sell them for over $24 if the price of each banana bread is $1.25 and the price of each nut bread is $1.50.

Michelle is debating between two different mortgages for $184,000. She found a 20-year fixed rate loan at 7.05% and 15-year fixed rate loan at the same rate. How much more interest will she pay for the 20-year loan versus the 15-year loan?

Answers

9514 1404 393

Answer:

  $45,081

Step-by-step explanation:

The amortization formula can be used to find the monthly payment.

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 20-year loan with r=0.0705 and P=184,000, the monthly payment is ...

  A = $1432.08

The total amount repaid will be ...

  12×20×1432.08 = 343,699.20

__

For the 15-year loan with the same parameters, the monthly payment is ...

  A = 1658.99

and the total amount repaid is ...

  12×15×1658.99 = 298,618.20

The difference in these repayment amounts is the difference in interest charges:

  343,699.20 -298,618.20 = 45,081

The 20-year loan will cost $45,081 more than the 15-year loan.
