The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is th
Crank

Answer:

One number is 4.2, the other is 18.8

Step-by-step explanation:

1.)  x+y=23

    (x+6y)x2=4

2.) (x+6y)x2=4   =   2x+12y=4

3.)Use elimination/substitution to solve

     2x+12y=4  =   x+6y=2  =  x=2-6y

     2-6y+y=23

4.)Solve for y

     2-5y=23 -> -5y=21 -> y=4.2.

5.)Solve for x

    x+4.2=23

    x=18.8

Given: CH bisects DHG.<br> mGF = (2x + 6)° and mDC = (7x – 1) ° <br> I cannot figure this one out.
Natalka [10]

Applying the definition of an angle bisector, the value of x is: 11.

<h3>What is an Angle Bisector?</h3>

When a line segment bisects an angle into two equal halves, it is called an angle bisector. The two small angles formed have equal measure.

Given that CH is the angle bisector of angle DHG

m(GF) = (2x + 6)°

m(DC) = (7x – 1)°

m(DC) = m(GC) = (2x + 6)° [congruent angle]

The measure of half a circle is 180 degrees.

Therefore, we would have the following equation that would enable us find the value of x:

2[m(DC)] + m(GF) = 180°

Plug in the values

2(7x – 1)° + (2x + 6)° = 180°

14x – 2 + 2x + 6 = 180

Combine like terms together

16x + 4 = 180

16x = 180 - 4

16x = 176

Divide both sides by 16

16x/16 = 176/16

x = 11

C) How many times would you expect to roll a 5 when<br> a fair dice is thrown 3000 times?
Ray Of Light [21]

Answer:

500

Step-by-step explanation:

The probability is 1/6.

So, find 1/6 of 3,000.

1/6 * 3,000 = 3,000/6 = 500
