Answer:
The missing reason is Subtraction Property of Equality.
Step-by-step explanation:
⇒ (Given)
On Solving we get;
Multiplying 2 on both side we get;

⇒ (Multiplication Property of Equality)
Now Subtracting Both side by 10 we get;

⇒ (Subtraction Property of Equality)
Now Dividing both side by 3 we get;

⇒ (Division Property of Equality)
Hence the missing reason is Subtraction Property of Equality.
Answer:
The answer is B because x = 4 so 12x4-3=45
Anddd Similar traingles for one more time.
Here,
RQ/RP = RS/RT = QS/PT = 1/2
Using the values of QS and PT will give,

Therefore y= 46 units.
Answer:
I can't help.
Step-by-step explanation:
There is no question, so therefore, I can not help.
For number 12 you need to make an expression using the information given. a) 25g + 18r + 15b could be the expression.
b) The variables would be 25g for the 25 gold seats, 18r for the 18 red seats and 15b for the 15 blue seats.
c) Plug in the number given according to the variables.
25(100) + 18(250) + 15(200)
2500 + 4500 + 3000
7000 + 3000
$10,000
