Answer:

Step-by-step explanation:

circumference of total circle = 16 pi

16 pi / 4 pi = 4

1 / 4 =25%

1/4 * 360 = 90

lisabon 2012 [21]

Answer: (10x + 30)

Step-by-step explanation:

1. combine like terms. -4x + 3x = -x

2. you can’t have a negative x, so you would multiply the equation (-x+3) by -1, to get (x-3).

3. (x-3)(10)... 10 • x = 10x, 10 • 3 = 30.

4. put them together, answer would be 10x + 30.

The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial point to a new location. Types of transformation are<em> reflection, rotation, translation and dilation.</em>

Dilation is the increase or decrease in size of a figure by a scale factor.

The larger figure was dilated using a scale factor of 5, hence:

Line K'O' = 5 * line KO

The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO

Which number line represents the solution to the inequality 125x + 200 > 1,200?

Elza [17]

Answer:

see below

Step-by-step explanation:

25x + 200 > 1,200

Subtract 200 from each side

25x + 200-200 > 1,200-200

25x> 1000

Divide by 25

25x/25 >1000/25

x>40

2x-y=-1 , 3x-y=2 solve by substition

Mazyrski [523]

Answer:

x = 3, y = 7

or (3,7)

Step-by-step explanation:

We are given the system of equations below:

$\large{ \begin{cases} 2x - y = - 1 \\ 3x - y = 2 \end{cases}}$

We are required to solve the system by substitution method. What we have to do is to isolate either x-term or y-term so we can use the method. I will be isolating y-term because it is faster due to having 1 as a coefficient.

By isolating y-term, just pick one of the given equations to isolate. No need to isolate the whole system. (I will be isolating y-term of the first equation.)

$\large{ \begin{cases} y= 2x + 1\\ 3x - y = 2 \end{cases}}$

Then we substitute y = 2x+1 in the second equation.

$\large{3x - (2x + 1) = 2}$

Use the distribution property.

$\large{3x - 2x - 1 = 2}$

Isolate x-term to solve the equation.

$\large{x = 2 + 1} \\ \large{x = 3}$

Since we are solving a system of equations. We have to solve for both x-value and y-value to complete. We have already found x-value, but nor y-value yet. Therefore, our next step is to substitute the value of x that we solved in any given equations. It's recommended to substitute in an equation that doesn't have high coefficient value. So I will be substituting x = 3 in the first equation.

$\large{2x - y = - 1} \\ \large{2(3) - y = - 1} \\ \large{6 - y = - 1}$

Isolate and solve for y-term.

$\large{6 + 1 = y} \\ \large{7 = y} \\ \large{y = 7}$

Since we substitute x = 3 and get y = 7. We can write in ordered pairs as (3,7)

Hence, the solution is (3,7)
