Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).
Given that a = two and b = 3, what is the value of (ab)?
Answer:
(ab) = 6
Step-by-step explanation:
a = 2 and b = 3
So, (2(3)) or 2 x 3 = 6

1) Find the distance between -49.75 and 31.5 on a number line.
Answer:
81.25
Step-by-step explanation:
Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.
Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.
Finally, add those two distances together so that you know the total distance:
49.75+31.5 = 81.25

Jayson gets a loan from his parents with no interest L represents the remaining amount Jayson owes his parents on his loan t months. L=-250t+7000 how much did Jayson borrow from his parents?
Answer:
7000
Step-by-step explanation:
Given the equation :
L=-250t+7000
L = amount owed after t months of repayment.
From the equation given, we could deduce that it is a linear equation of the form :
y = bx + c
Where, b = - 250 is the slope = fixed amount paid per month and it's negative because the amount owed will reduce with each payment made.
c = intercept, which is the value of L when t = 0
This will give amount borrowed :
L=-250t+7000
At t = 0
L = - 250(0) + 7000
L = 7000
write an equation of the line in slope-intercept form.

Answer:362
Step-by-step explanation:
So, the ones digit is 2. Since the hundreds digit is one more, it's 3. And because the tens is twice the hundreds, it's 6. The number is 362

Presale tickets (p) are each worth $7: represented in the equation as 7p.
Door tickets (d) are each worth $10: represented in the equation as 10d.
They sold 345 tickets, so p+d=345. They collected $2550, so 7p+10d=2550.
Final answer:

Answer:
-4 19/20
Step-by-step explanation:
2 1/5 ÷ -4/9
Change to an improper fraction
(5*2+1)/5 =11/5
Copy dot flip
11/5 * -9/4
-99/20
Changing back to mixed number
-4 19/20
Answer:
-99/20 or -4.95
Step-by-step explanation:
make the first fraction a simple fraction by multiplying the denominator by the whole number and adding the numerator.
which equals 11/5. Then you multiple by the reciprocal of 4/-9 which is -9/4
to look like 11/5 * -9/4 = -99/20

A submarine begins its descent from the surface of the water and dives 20 feet for each minute. What would be the depth of the submarine after 2/3 hours?
Answer:
Distance = speed * time
Convert feet to meter (C units) = about 6
Convert hours to second (C units) = about 2399
Distance = 6 * 2399
= 1439 meters
