Answer:

9/2 or if that doesn't work try 4 1/2

Step-by-step explanation:

The probably of getting a plain pencil from the first box is 9/10. The probability of getting a color pencil from the second box is 5/10. If you multiply those you get 9/2 or 4 1/2.

Solving the following system using the elimination or the substitution method.
Lina20 [59]

Answer and Step-by-step explanation:

For these system of equations, it would be easier to use the substitution method, as we are have one equation that is being equaled to a variable.

Plug the second equation into the value of b for the first equation.

5a + 3(-2a + 3) = 11

Distribute the 3.

5a - 6a + 3 = 11

Simplify.

-a + 3 = 11

Subtract 3 from both sides of the equation.

-a = 8

Divide both sides by -1.

a = -8

Now, we can plug this value into the second equation.

-2(-8) + 3 = b

Multiply -2 and -8 together.

16 + 3 = b

Add together 16 and 3.

19 = b

<u>a = -8</u>

<u>b = 19</u>

Order the steps for bisecting line segment AB using a reflective device.
yulyashka [42]

The question requires that segment AB is to be divided into two equal parts.

To do this, the order of steps for bisecting AB are D, E, B, C, A

To bisect segment AB implies dividing AB into two equal parts. After the construction, the length of each part must be equal.

Therefore, the required steps to bisect segment AB are as follow

<h3>What reflective device?</h3>

A MIRA is a commercial name given to a piece of colored transparent plastic used to reflect geometric objects.

D. Place the compass on point A, and open it wider than half the distance of the segment.

E. Swing an arc above and below the segment.

B. Keeping the compass the same width, place the compass on point B, and swing an arc above and below the segment.

C. Place points C and D on the intersection of the arcs created above and below segment AB.

A Draw a line from C point to point D.

Therefore the line CD is the perpendicular bisector of segment AB.

Thus, the order of steps for the bisection process is D, E, B, C, and A.
