Which statement explains why –27 is the opposite number of 27? Answer Choices They are the same quantity with different signs. They are an equal distance from 1 on the number line. They are both greater than 0. They are odd numbers.

Answers

Now... -27 and 27 are equally the same number, but in different signs, but they are also same distance from each other. So i'd say: They are the same quantity with different signs.
"They are the same quantity with different signs" is the answer, 27 and -27 are the same  number ( quantity) just one is a positive number and the other is a negative number.

What are the solutions to the system of equations?

Answers

Answer:

A. (1,5) and (5,13)

Step-by-step explanation:

We have been given a system of equations. We are asked to find the solution of our given system.

\left \{ {{y=x^2-4x+8}\atop {y=2x+3}} \right.

Equate both equations:

x^2-4x+8=2x+3

x^2-4x-2x+8-3=2x-2x+3-3

x^2-6x+5=0

Split the middle term:

x^2-5x-x+5=0

x(x-5)-1(x-5)=0

(x-5)(x-1)=0

Use zero product property:

(x-5)=0\text{ (or) }(x-1)=0

x=5\text{ (or) }x=1

Now, we will substitute both values of x, in our given equation to solve for y.

y=2x+3

y=2(1)+3

y=2+3

y=5

One solution: (1,5)

y=2x+3

y=2(5)+3

y=10+3

y=13

2nd solution: (5,13)

Therefore, option A is the correct choice.

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = x² - 4x + 8 → (1)

y = 2x + 3 → (2)

Since both express y in terms of x we can equate the left sides, that is

x² - 4x + 8 = 2x + 3 ( subtract 2x + 3 from both sides )

x² - 6x + 5 = 0 ← in standard form

(x - 1)(x - 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 5 = 0 ⇒ x = 5

Substitute these values into (2) for corresponding values of y

x = 1 : y = (2 × 1) + 3 = 2 + 3 = 5 ⇒ (1, 5)

x = 5 : y = (2 × 5) + 3 = 10 + 3 = 13 ⇒ (5, 13)

Solutions are (1, 5) and (5, 13)

18 is 45% of what numbet

Answers

Part/Whole=Percent/100
Part=18
Percent=45
Whole= a variable that we are trying to figure out
so now its 18/x=45/100
Cross multiply and get 
45x=1800
Divide by 45 and get 40. 18 is 45%of 40

The number that 18 is 45% of  40.

To find the number that 18 is 45% of, we can set up the following equation:

we can set up the following equation:

Given number is 18 and the percentage is  45%

18 = 0.45 * x

x=18/0.45

To solve for x, divide both sides of the equation by 0.45:

To solve for x, divide both sides of the equation by 0.45:

x = 18 / 0.45

x=40

By future Performing the calculation:

x = 40

We get the answer as 40.

Therefore, 18 is 45% of 40.

Given figure ABCD ~ figure WXYZ, what is the value of k? m In quadrilateral ABCD, the length of segment CD is two and three-tenths meters and the length of segment BC is four and two-tenths meters. In quadrilateral WXYZ, the length of segment YZ is unknown and represented by variable k, and the length of segment XY is eight and four-tenths meters.

Answers

You can use ratio and proportion in this problem.

Segment DC / Segment CB = Segment ZY / Segment YX

2.3m / 4.2m = k / 8.4m

K = 8.4 (2.3 / 4.2)

K = 23/5 or 4.6 m 

Answer= 4.6 m

12.5 is 25% of what number

Answers

12.5 is 25% of x
percent means parts out of 100
25%=25/100=1/4
12.5=1/4 of a number
mulitply both sides by 4
50=number

the number is 50
Since 25% is 1/4 of 100%, then you do 12.5 times 4 to get 50.
