Answer 1

Answer:

-31/4

Step-by-step explanation:

[tex]\frac{1}{2} ^{2}[/tex] is actually just (1/2)(1/2) and that equals 1/4

2 - (2/3) you can simplify to (6/3) - (2/3). that equals 4/3

now put it together!

(1/4) - 6(4/3)

(1/4) - (24/3) --------> (which simplifies to 8)

1/4 - 8 ----> (now you have to simplify this to match 1/4 denominator)

(1/4) - (32/4)

-31/4

Answer:10

Step-by-step explanation:

A local foundation organized a lunch party for all the kids in the community. They ordered a total of 500 burger meals. They ordered plain burgers at $1.75 each cheeseburgers at $2.50 each, and chicken burgers
at $3.20 each. They ordered mostly cheeseburgers, and 100 fewer chicken burgers than plain burgers. The total order came to $1.172.50.
Define the variables and write a system of equations to represent the
situation.

Answer:

x + y + z = 5002.50x +1.75y +3.20z = 1172.500x +y -z = 100

Step-by-step explanation:

Let x, y, z represent the numbers of cheeseburgers, plain burgers, and chicken burgers ordered for the party.

We have three relations given. Each can be used to write an equation.

  x + y + z = 500 . . . . . . . . . a total of 500 meals were ordered

  2.50x +1.75y +3.20z = 1172.50 . . . . . the total cost

  0x +y -z = 100  . . . . . . . . . . 100 fewer chicken were ordered than plain

Additional comment

We put the coefficient of x as 0 in the last equation to facilitate writing this system as an augmented matrix.

|8w+5|=21
please show work

Answers

Answer:

w=-13/4

w=2

Step-by-step explanation:

|8w+5|=21

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |8w+5| = 21

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |8w+5|

For the Negative case we'll use -(8w+5)

For the Positive case we'll use (8w+5)

STEP

3

:

Solve the Negative Case

     -(8w+5) = 21

    Multiply

     -8w-5 = 21

    Rearrange and Add up

     -8w = 26

    Divide both sides by 8

     -w = (13/4)

    Multiply both sides by (-1)

     w = -(13/4)

    Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

     (8w+5) = 21

    Rearrange and Add up

     8w = 16

    Divide both sides by 8

     w = 2

    Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

w=-13/4

w=2

In the year 2015 Emily was three times as old asKaitlin. By the year 2021 Kaitlin will be half asold as Emily will be. How old was Emily on theyear 2000?

Answers

In 2000 Emily was 9 years old.

Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:

2015 = E = 3K 2021 = E = 2K  24 /// 8 --- 30 /// 14 18 /// 6 --- 24 /// 12 18/6 = 3 24/12 = 2 2015 = Emily was 24 years old 24 - (2015 - 2000) = X 24 - 15 = X 9 = X

Therefore, in 2000 Emily was 9 years old.

Answer:

Question 1: [tex]x=4[/tex]

Question 2: [tex]x= \pm7[/tex]

Question 5: The dimensions of one face of the container are 6 by 6 inches.

Step-by-step explanation:

Hi there!

Question 1

[tex]x^3=64[/tex]

Rewrite 64 as a power of 3:

[tex]x^3=4^3[/tex]

(We could find that 4³ = 64 through trial and error)

This above equation makes it true that x=4. If aⁿ = bⁿ, then a=b:

[tex]x=4[/tex]

Question 2

[tex]x^2=49[/tex]

Rewrite 49 as a power of 2:

[tex]x^2=7^2[/tex]

Again, we could have found this through trial and error, or by looking at our multiplication tables.

[tex]x=7[/tex]

However, remember that positive and negative numbers will all square to be a positive number. So, therefore, x can be -7 OR 7 (since both, when squared, equal 49):

[tex]x= \pm7[/tex]

Question 5

Let x be equal to the length of one edge of the cube.

Volume of a cube formula: [tex]V=x^3[/tex]

Plug in the given information, when V is the volume:

[tex]216=x^3[/tex]

Rewrite 216 as a power of 3:

[tex]6^3=x^3[/tex]

^ We could have found this through trial and error.

[tex]x=6[/tex]

Therefore, the dimensions of one face of the container are 6 by 6 inches.

what is the slope of a line b perpendicular to line a with equation y=7x-9

Answers

Answer:

The slope of line b would be -1/7.

Step-by-step explanation:

This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.

Then, all you need to do is find some points and graph the lines.
