Answer:
a
Step-by-step explanation:
Presumably our goal is to show PRQ=SRQ, PQR=SQR and QR=QR for ASA.
A. QR=QR is the reflexive property; things are congruent to themselves, TRUE
B. We need to prove that, but it doesn't have anything to do with the symmetric property.
C. PQ=SQ isn't something we'd need to show for our ASA proof
D. Again, not the symmetric property.
Answer: A
Answer:
14
Step-by-step explanation:
B is the midpoint of AC, in other words it is the halfway point.
So A to B should be equal to B to C
Our expression is:
2x + 9 = 37
Subtract 9
2x = 28
Divide by 2
x = 14
Answer: 0.1 or 1/10
Step-by-step explanation:
Cross, cancel common factor
System of Equations
For the problem to solve we'll use the following variables:
x = number of the early bird tickets sold
y = number of the regular tickets sold
Haley sold a total of 20 tickets, thus:
x + y = 20 [1]
Early bird tickets cost $10 and regular tickets cost $15, thus the total money collected is:
10x + 15y = 225
Dividing by 5:
2x + 3y = 45 [2]
We have to solve the system of equations [1] and [2].
Multiply [1] by -2:
-2x - 2y = -40 [3]
Add [3] to [2]:
-2x - 2y +2x + 3y = -40 + 45
Simplifying:
y = 5
Substituting in [1]:
x + 5 = 20
Subtracting 5:
x = 20 - 5
x = 15
Solution: Hayley sold 15 early bird tickets and 5 regular-priced tickets
The order pair solution is (15,5)
