shoes?

Answer:

6

Step-by-step explanation:

|-6| = 6

Answer:

6

Step-by-step explanation:

you can also understand absolute value as the distance in the number line from -6 to 0

and that's 0-(-6)

=6

so

|-6|=6

Answer:

15 days

Step-by-step explanation:

a) Li uses = 8.4 grams of sugar every day in her tea.

Li’s sugar canister contains = 128 grams of sugar

Let x be the number of days at which Li uses sugar in her tea

The Equation for Li's sugar usuage =

y = 128 - 8.4x ......... Equation 1

Where y , the quantity of sugar left.

b) Sue uses = 12.6 grams of sugar every day in her coffee.

Sue’s canister contains = 191 grams

Let x be the number of days at which Sue uses sugar in her tea

The Equation for Sue's sugar usuage =

y = 191 - 12.6x .........Equation 2

Where y , the quantity of sugar left.

We are asked in the question, how many days will Li and Sue have the same amount of sugar in their canisters

We would equate both equations to each other.

Equation 1 = Equation 2

y = 128 - 8.4x = y = 191 - 12.6x

128 - 8.4x = 191 - 12.6x

-8.4x + 12.6x = 191 - 128

4.2x = 63

x = 63/4.2

x = 15

15 days

Therefore Li and Sue have the same amount of sugar in their canisters after 15 days.

To confirm

Equation 1 = Equation 2

y = 128 - 8.4x = y = 196 - 12.6 × 15

y = 128 - 8.4 × 15 = y = 196 - 12.6 × 15

y = 128 - 126 = y = 196 - 189

y = 2 = y = 2

Answer:

1 pint=32    1 quart=64    1 gallon=256

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

To simplify this expression, we will simply work with the numerator, then the denominator, and then the fraction as a whole, following PEMDAS.

Numerator:  12 - 6 + 5 * (-3)^2

= 12 - 6 + 5 * (9)

= 12 - 6 + 45

= 6 + 45

= 51

Denominator:  17

So our simplified fraction is as follows:

51/17

Which can be reduced to the whole number, 3.

Cheers.

Answer:

Step-by-step explanation:

The midpoint M of a line segment with two endpoints can be found using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question

The endpoints are (-2,-4) and (6,8)

The midpoint is

[tex]M = ( \frac{ - 2 + 6}{2} , \frac{ - 4 +8 }{2} ) \\ = ( \frac{4}{2} , \frac{ 4 }{2} )[/tex]

We have the final answer as

Answer:

A. 2^-6

C. 4^-3

Step-by-step explanation:

Iris found a value of 1/64 when she evaluated an expression.

Which could have been the expression Iris evaluated? Check all that apply.

A. 2^-6

B. 6^-4

C. 4^-3

D. (1/2)^-5

E. (1/4)^-3

A. 2^-6

= 1 / 2^6

= 1 / 2*2*2*2*2*2

= 1 / 64

B. 6^-4

= 1 / 6^4

= 1 / 6*6*6*6

= 1 / 1,296

C. 4^-3

= 1 / 4^3

= 1 / 4*4*4

= 1 / 64

D. (1/2)^-5

= 1 ÷ (1/2)^5

= 1 × 2/1^5

= 2^5

= 2*2*2*2*2

= 32

E. (1/4)^-3

= 1 ÷ (1/4)^3

= 1 × 4/1^3

= 4^3

= 4*4*4

= 64

Options A. 2^-6 and C. 4^-3 are equivalent to 1/64

Answer:

y=8x

Step-by-step explanation:

There is no why intercept because there is no additional boarding fee, so the only part of the equation you get is y=mx.  In this equation, that is y=8x, where "x" is the number of hours in the cab, 8 represents the cost per hour, and "y" is the total cost of the entire cab ride.

Answer:

Answer:

n = 10

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

-2 = -(n - 8)

Step 2: Parenthesis (distribute)

-2 = -n + 8

Step 3: Subtract 8 on both sides

-10 = -n

Step 4: Divide both sides by -1

10 = n

Step 5: Rewrite

n = 10

Answer:

[tex]n=10[/tex]

Step-by-step explanation:

So we have the equation:

[tex]-2=-(n-8)[/tex]

First, divide both sides by -1. The left will become positive, and the negative in front of the parentheses will be canceled:

[tex](-2)/-1=(-(n-8))/-1\\2=n-8[/tex]

Add 8 to both sides. The right cancels:

[tex]2+8=(n-8)+8\\n=10[/tex]

So, the value of n is 10.

And we're done!

Answer:

8 or 32

Step-by-step explanation:

So we are given two coordinates and the length of the segment formed by those coordinates.

To find the unknown coordinate, we can use the distance formula. Let the unknown value be n:

Let's let (-2,n) be x₁ and y₁ and let (-7,20) be x₂ and y₂.

The distance formula is given by the formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute (-2,n) for x₁ and y₁ and (-7,20) for x₂ and y₂. Also, since we already know that the length is 13, substitute it for d. Thus:

[tex](13)=\sqrt{((-7)-(-2))^2+((20)-(n))^2}[/tex]

Do the operations within the parentheses:

[tex]13=\sqrt{(-7+2)^2+(20-n)^2}\\13=\sqrt{(-5)^2+(20-n)^2}[/tex]

Now, square both sides to take out the square root:

[tex](13)^2=(\sqrt{(-5)^2+(20-n)^2})^2[/tex]

Simplify:

[tex]169=(-5)^2+(20-n)^2[/tex]

Square (-5):

[tex]169=25+(20-n)^2[/tex]

Subtract 25 from both sides. The right cancels:

[tex](169)-25=(25+(20-n)^2)-25\\144=(20-n)^2[/tex]

Now, take the square root of both sides.

[tex]\pm\sqrt{144}=\sqrt{(20-n)^2}[/tex]

Simplify:

[tex]\pm12=(20-n)[/tex]

So, we have two solutions:

[tex](12=20-n)\text { or }(-12=20-n)[/tex]

On the left, subtract 20. On the right, also subtract 20:

[tex](-8=-n)\text { or }(-32=-n)[/tex]

Divide both sides by -1:

[tex](n=8)\text{ or } (n=32)[/tex]

So, our two possible answers are 8 or 32.
