solve for X
Please walk me through the steps, I understand most of it I just forgot how to do it
Answers
Answer:
x=8
Step-by-step explanation:
first you need to find the unknown corner so you do 180-71= 109
then find the interior angle degree (n-2)*180 (n=number of sides) so (4-2)*180=2(180)=360
then set everything equal to 360:
10x+6+13x-2+8x-1+109=360
(combine like terms)
31x+112=360
(subtract 112 form both sides)
31x=248
(divide both sides by 31)
x=8

A. 10
B. 15
C. 20

Answers
Answer:
39/40
Step-by-step explanation:
Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.
However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)

The sum of two consecutive integers is 81. Determine the lesser of the two numbers.
Answers
Given that,
the two numbers are consecutive
The two numbers are
x and x + 1
Sum of the numbers = 81
x + (x + 1) = 81
x + x + 1 = 81
2x = 81 - 1
2x = 80
x = 80/2
x = 40
Therefore, the two numbers are x = 40 and x + 1 = 41
