The product of any integer and zero is zero
First distribute the 3
12y - 15 = 69
Subtract -15 from both sides
12y = 84
<u>y=7</u>
PROOF:
3 (4 *7 - 5)
3 (28-5)
3 (23) = 69
The conclusion based on the mean of the ball and the distance traveled is D. Inferences cannot be made about all the golf balls produced on that day.
<h3>How to deduce the inference?</h3>
From the information given, a golf pro randomly selects a ball, not knowing the type of ball, hits it and end of the session, the mean distance traveled for the new type of golf ball was found to be greater than the mean distance for the original-style golf ball.
In this case, inferences cannot be made about all the golf balls produced on that day; however, the conclusion can be made that the new type of golf balls travel farther than the original type of golf ball for this golf pro.

Answer:
x=127
Step-by-step explanation:
total sum of all angle of triangle is 180 degree
Now,
taking angle A let interior angle be Y
taking angle C let interior angle be Z
Again, In angle A
the sum of interior angle and exterior angle is 180 degree being staright line
Or, y+(x+5)=180
or,x+y=180-5
or, x+y=175
or,y=175-x --------eqn 1
In angle C
the sum of interior angle and exterior angle is 180 degree being staright line
or, x+z=180
or, z=180-x ----------eqn2
Again, In triangle ABC
total sum of all angle of triangle is 180 degree.
Angle A+ Angle B + AngleC=180
Or, y+79+z=180 -------eqn3
putting the value of eqn-1 and eqn-2 in eqn-3
Or, 175-x+79+180-x=180
Or, 431-180= 2x
Or, 254÷2=x
hence X= 127 degree
The simplified answer is 12k -1
Hope this helps!!!!!!!!1
