Answer:

Open circle. Points right

Step-by-step explanation:

The reason for it is because this symbol > represents greater than when it comes to inequalities. When it is an open circle that means that you are not including the number. So that also means that the -2.5 is not included to the inequality equation but it can be any other number other than that number.

Answer:

$W=(x-6)\ m$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

we have

$A=(x^{2} -11x+30)\ m^2$

$L=(x-5)\ m$

substitute the given values in the formula of area

$(x^{2} -11x+30)=(x-5)W$

Remember that

$x^{2} -11x+30=(x-5)(x-6)$ ----> by completing the square

substitute

$(x-5)(x-6)=(x-5)W$

Simplify

$W=(x-6)\ m$

If i sold 3 small boxes of oranges and 14 large boxes of oranges for total of $183. how much are the small and large box

Liono4ka [1.6K]

X = small boxes and y = large boxes

x + y = 17.....x = 17 - y
3x + 14y = 183

3(17 - y) + 14y = 183
51 - 3y + 14y = 183
-3y + 14y = 183 - 51
11y = 132
y = 132/11
y = 12 <=== large boxes (y) cost $ 12

x + y = 17
x + 12 = 17
x = 17 - 12
x = 5 <=== small boxes (x) cost $ 5

Jaime adds equations A and B to solve this system of equations. Why is this method

just olya [345]

The elimination method is valid for the system of equation because the y term cancels.

<h3>How to solve a system of equation using elimination method?</h3>

The system of equation can be solved using elimination methods.

Therefore,

x - 2y = 3

3x + 2y = 17

Hence,

x + 3x = 4x

-2y + 2y = 0

3 + 17 = 20

Therefore,

4x = 20

The y term cancels. Therefore, we can solve for x and later solve for y.
