I need help understanding this problem.​
kobusy [5.1K]

Answer:

59

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to the exterior angle

4x+11  +51  = 10x -10

Combine like terms

4x+62 = 10x -10

Subtract 4x from each side

4x+62-4x = 10x-10-4x

62 = 6x-10

Add 10 to each side

62+10 = 6x-10+10

72 = 6x

Divide by 6

72/6 = 6x/6

12 =x

We want to find angle D

<D =4x+11

     = 4*12 +11

    = 48+11

    = 59

Sample space: {Black, Red, Blue, Brown, Purple, Yellow, Green}

Simple event

Step-by-step explanation:

Sample space is a list of all the possible outcomes.

This is a simple event because you are only doing one event, such as choosing marbles from a bag.

A compound event would be multiple simple events, such as flipping a coin <em>and</em> rolling a dice.

Jessica's Running Journal
Mashcka [7]
I believe all you have to do is add the amount of miles she ran in each weeks to get the total amount of miles she ran in two weeks! So, 11.9 + 15.05 = 26.95
So, Jessica ran 26.95 miles in the two weeks! I hope this helps!! :)
