Answer:
1080 degrees
180(n-2) = sum of all interior angles
180(6) = 1080
Answer:
5.5, 9.5
Step-by-step explanation:
Let x and y be the numbers
x+y = 15
x-y = 4
Add the two equations together to eliminate y
x+y = 15
x-y = 4
------------------
2x = 19
Divide by 2
2x/2 =19/2
x = 9.5
Now find y
x+y = 15
9.5+y = 15
Subtract 9.5
x = 15-9.5
x =5.5
Answer:
B
Step-by-step explanation:
Plug in all the values for x & y into the equation y=2x+3 (B). 2*2=4. 4+3=7. All the other values for x & y match up perfectly as well. The answer is B
