Answer:
A | 4.50 Per Person
Step-by-step explanation:
If it's 9.00 for 2 people. 9 divided by 2 is 4.50. Meaning it's $4.50 dollars for one person.
The radius of a circle is half the length of the diameter so
radius=1.5m
Well you have to substitute the 4 in for X. It would make the equation: 3(4)+6=18. (Multiply 3 and 4)
12+6=18 (Add 12 and 6)
18=18
Hope this helped :)
Answer:

7x-2y=37
[2(4x+y=19)]=
8x+2y=38
---------------------
15x/15=75/15
x=5
[4(5)+y=19]
y=-1
