M1 = 65°
M2= 75°
all three angles is 180°
M7 = 40°
7 and 6 are identical angles corresponding
M6= 40°
Answer:
Solution (4,3)
Step-by-step explanation:
2x-7y= -13
<u>(8x-7y=11)x-1</u>
2x-7y= -13
-8x +7y= -11

x= 4
__________
2x-7y= -13
2(4)-7y=-13
8-7y= -13
subtract 8 from both sides

divide by -7
y= 3
hope it helps..
have a great day!!
Answer:
x(6 + 15y)
Step-by-step explanation:
In this instance, you can divide by a factor of x.
6x/x = 6
15xy/x = 15y
Therefore, we are left with 6 + 15y.
Answer:
The required probability (P) is :

Step-by-step explanation:
Probability of meeting random person who has same birthday as you = 
Probability of meeting random person who do not has same birthday as you =

Now, to find the required probability that the 25th person you meet is the first person who has the same birthday as you = (Probability that the first 24 persons we meet did not have same birthday as you) × (Probability that the first 25 persons we meet has same birthday as you)
Therefore,
