Point m is the midpoint of ab¯¯¯¯¯ . am=3x+3, and ab=8x−6. what is the length of am¯¯¯¯¯¯ ?
LuckyWell [14K]
As given m is a midpoint of ab. So am is half of ab.

So we can write

am =  \frac{ab}{2}

As given am = 3x+3 , ab = 8x - 6.

So 3x+3 = \frac{8x - 6}{2}

3x+3 =  \frac{2(4x - 3)}{2}

3x+3 = 4x - 3

3+3 = 4x - 3x


6 = x

So x = 6.

So length of am = 3x+3 = 3*6 + 3 = 21

A bag contains 5 white, 3 black, and 2 green balls. Balls are picked at random.
Soloha48 [4]

Answer:

look down there

Step-by-step explanation:

First ball:

Probability of drawing a white ball is 5/8

Probability of drawing a black ball is 3/8

Second ball:

This depends on the first ball drawn, lets say you drew a white ball initially, 4 white balls are left out of 7 balls in total. The probability of a white ball in the second pick is 4/7.

Total probability of drawing two white balls is 5/8*4/7 (since they are independent events).

If you picked a black ball initially, picking another black ball would have a probability of 2/7, on similar grounds , total prob for 2 blacks would be 3/8*2/7.

The probability that you pick 2 balls of same color is (5/14 + 3/28) = 13/28. (Since they are mutually exclusive events)

Find the value of x if ∡A and ∡B are supplementary angles.
Elanso [62]

Answer:

x = 30.5

Step-by-step explanation:

Two angles are supplementary when they add up to 180°.

So we know that:

C + D = 180

Supplanting we get:

(3x-44) + (5x-20) = 180

We add up the X's.

8x-44-20 = 180

8x-64 = 180

Then we send 64 to the other side adding:

8x = 180+64

8x = 180+64

8x = 244

And then the 8 goes dividing:

x = 244 : 8

x = 30.5
