Answer:
X= 20
Step-by-step explanation:
Since the they are both interior angles they can be set equal to each other.
-9-9x+4=159+159x+4=-5
-5-9x=163+159x=-5
+5 +5
-9x=168+159x=-5
+9x +9x
168+168x=-5
-168 -168
168x=-173
x=
Answer:
5/19
Step-by-step explanation:
Marbles=20
So the probability of choosing not yellow is 10/20=1/2.
Marbles are not replaced.
The total number is 19
The probability of choosing yellow is 10/19
So the final answer is (1/2)*(10/19)=5/19.

B, the pipe drops too much vertically to function properly.
We start off knowing the horizontal distance, 45 feet. We multiply that by 12 to convert it to inches, and we get 540. Now, we divide 540 by 25 to find out how many inches the pipe needs to drop. Turns out, 540/25 is 21.6, so 25 isn’t the exact inches we need it to drop. It drops too much.
