I can't understand this after "happening is" but let's do it unaided.
The number of ways to draw a boy first is 6.
Given that, the number of ways to draw a girl next is 10.
That's out of a total of 16 x 15 length two permutations of 16 things

Answer: 1/4
4-2d<4
-2d>0
d>0 the answer to the question
There shouldn't be a negative in front of one of the equations.
Answer:
x = 125
Step-by-step explanation:
Ok so we already established that AIA are congruent. So two angles will equal 55 degrees. All angles in a parallelogram add up to 360 degrees, and there are two pairs of matching angles opposite of each other.
So we take the two 55 degree angles and subtract them from 360:
360-110 = 250
Now there are two identical angles left, one of them is x, that equal a total of 250, so divide by two:
250/2
=125 degrees
Sum of a number and 7 = x + 7
Is 11 = "= 11"
That equals x + 7 = 11.
x = 4
Hope this helped☺☺
