That would be -21.
-6-15= -6+(-15)
15+6 is 21. They were both negatives, so we stick with the negatives and get -21
Answer:
If I could travel to any year in a time machine, I would choose a year in future. For example, 3050. Everyone assumes the future according to their own imagination. But nobody knows what it actually looks like. So, if I could time travel, I would travel to a year in future.
If line AB and BC are intersecting at point B and ray BD bisect the angle ABC, then the value of x is 23
The line AB and BC are intersecting at point B.
Ray BD bisect the angle ABC
∠ABD = x+8 degrees
∠ABD=∠DBC = x+8
Because the ray BD bisect the ∠ABC, so ∠ABD and ∠DBC will be equal
∠ABD+∠DBC= 4x-30 degrees
Because both are vertically opposite angles
Substitute the values in the equation
x+8 + x+8 = 4x-30
2x+16 = 4x-30
2x-4x = -30-16
-2x = -46
x = 23
Hence, if line AB and BC are intersecting at point B and ray BD bisect the angle ABC, then the value of x is 23

Answer:
25
Step-by-step explanation:
The answer is 25. Here is a solution using the formulas:
For 3_1_1
(5C3*2C1*1C1)/2! = 10
For 2_2_1
(5C2*3C2*1C1)/2! = 15
10+15=25
Not 100% sure just double check
Answer:
The distance between Shawna's Home and Rochester is 228 mi and takes her 6 hr to make the drive.
Step-by-step explanation:
<u>Known Data</u>
Final distance is the same for both , but for Terrence , due he didn't arrive for 56 mi
Initial distance is the same for both
Shawna's Velocity , and time
Terrence's Velocity , and time, as he starts 2hr later
<u>Formula</u>
, for both cases
<u>Equation System</u>
Shawna: or (1)
Terrence: , , and finally (2)
By solving this equation system (1) and (2), using any method, we obtain and .
